Description: # Fortuna: Fast & Flexible Random Generators
        Fortuna replaces some of the functionality of Python's builtin Random module with specialized high performance functions, often achieving 10x performance. However, the more interesting bits of Fortuna are found in the high-level abstractions like FlexCat and QuantumMonty.

        ## Fortuna Random Functions
        ### Random Numbers
        `Fortuna.random_range(lo: int, hi: int) -> int`. Returns a random integer in range [lo..hi] inclusive. Up to 15x faster than `random.randint()`. Flat uniform distribution.
        
        `Fortuna.random_below(num: int) -> int`. Returns a random integer in the exclusive range [0..num) for positive values of num. Flat uniform distribution.
        
        `Fortuna.d(sides: int) -> int`. Represents a single die roll of a given size die.
        Returns a random integer in the range [1..sides]. Flat uniform distribution.
        
        `Fortuna.dice(rolls: int, sides: int) -> int`. Returns a random integer in range [X..Y] where X = rolls and Y = rolls * sides. The return value represents the sum of multiple rolls of the same size die. Geometric distribution based on the number and size of the dice rolled. Complexity scales primarily with the number of rolls, not the size of the dice.
        
        `Fortuna.plus_or_minus(num: int) -> int`. Negative and positive input values of num will produce equivalent distributions. Returns a random integer in range [-num..num]. Flat uniform distribution.
        
        `Fortuna.plus_or_minus_linear(num: int) -> int`. Negative and positive input values of num will produce equivalent distributions. Returns a random integer in range [-num..num]. Zero peak geometric distribution, up triangle.
        
        `Fortuna.plus_or_minus_curve(num: int, bounded: bool=True) -> int`. Negative and positive input values of num will produce equivalent distributions. Returns a random integer in range [-num..num]. If bounded is False, less than 0.1% of the results will fall outside the target range by up to +/- num. This will not change the overall shape of the distribution curve. Zero peak gaussian distribution, stretched bell curve: mean = 0, variance = num / pi.
        
        `Fortuna.zero_flat(num: int) -> int`. Returns a random integer in range [0..num]. Flat uniform distribution.
        
        `Fortuna.zero_cool(num: int) -> int`. Returns a random integer in range [0..num]. Zero peak, geometric distribution, half triangle.
        
        `Fortuna.zero_extreme(num: int) -> int`. Returns a random integer in range [0..num]. Zero peak, gaussian distribution, half bell curve: mean = 0, variance = num / pi.
        
        `Fortuna.max_cool(num: int) -> int`. Returns a random integer in range [0..num]. Max peak (num), geometric distribution, half triangle.
        
        `Fortuna.max_extreme(num: int) -> int`. Returns a random integer in range [0..num]. Max peak (num), gaussian distribution, half bell curve: mean = num, variance = num / pi.
        
        `Fortuna.mostly_middle(num: int) -> int`. Returns a random integer in range [0..num]. Middle peak (num / 2), geometric distribution, up triangle. Ranges that span an even number of values will have two dominant values in the middle, this will guarantee that the probability distribution is always symmetrical.
        
        `Fortuna.mostly_center(num: int) -> int`. Returns a random integer in range [0..num]. Middle peak (num / 2), gaussian distribution, bell curve: mean = num / 2, variance = num / pi.
        
        ### Random Truth
        `Fortuna.percent_true(num: int) -> bool`. Always returns False if num is 0 or less, always returns True if num is 100 or more. Any value of num in range [1..99] will produce True or False based on the value of num - the probability of True as a percentage.
        
        ### Random Sequence Values
        `Fortuna.random_value(arr) -> value`. Returns a random value from a sequence (list or tuple), uniform distribution, non-destructive. Up to 10x faster than random.choice().
        
        `Fortuna.pop_random_value(arr: list) -> value`. Returns and removes a random value from a sequence list, uniform distribution, destructive. Not included in the test suite due to it's destructive nature. This is the only destructive function in the module, use with care. It will raise an error if the list is empty.
        
        ### Random Table Values
        `Fortuna.cumulative_weighted_choice(table) -> value`. Core function for the WeightedChoice base class. Produces a custom distribution of values based on cumulative weights. Requires input format: `[(weight, value), ... ]` sorted in ascending order by weight. Weights must be unique positive integers. See WeightedChoice class for a more comprehensive solution that verifies and optimizes the table. Up to 15x faster than random.choices()
        
        ### Utility Functions
        `Fortuna.min_max(num: int, lo: int, hi: int) -> int`. Used to force a number in to the range [lo..hi]. Returns num if it is already in the proper range. Returns lo if num is less than lo. Returns hi if num is greater than hi.
        
        `Fortuna.analytic_continuation(func: staticmethod, num: int) -> int`. Used to map a positive only function to the negative number line for complete input domain coverage. The "C" version of this function is used throughout the Fortuna extension. The function to be analytically continued must take an integer as input and return an integer.
        
        ## Fortuna Random Classes
        ### Sequence Wrappers
        #### Random Cycle: The Truffle Shuffle
        Returns a random value from the sequence. Produces a uniform distribution with no consecutive duplicates and relatively few nearly-consecutive duplicates. Longer sequences will naturally push duplicates even farther apart. This behavior gives rise to output sequences that seem much less mechanical than other random value sequences.
        
        - Constructor takes a copy of a sequence (list or tuple) of arbitrary values.
        - Sequence length must be greater than three, best if ten or more.
        - Values can be any Python object that can be passed around.
        - Features continuous smart micro-shuffling: The Truffle Shuffle.
        - Performance scales by some small fraction of the length of the sequence.
        
        ```python
        from Fortuna import RandomCycle
        
        
        random_cycle = RandomCycle(["Alpha", "Beta", "Delta", "Eta", "Gamma", "Kappa", "Zeta"])
        
        random_cycle()  # returns a random value, cycled uniform distribution.
        random_cycle(n_samples=10)  # returns a list of 10 random values, cycled uniform distribution.
        ```
        
        #### The Quantum Monty
        A set of strategies for producing random values from a sequence where the probability
        of each value is based on the monty you choose. For example: the mostly_front monty
        produces random values where the beginning of the sequence is geometrically more common than the back. The Quantum Monty Algorithm results from overlapping the probability waves of six of the other eight methods. The distribution it produces is a gentle curve with a bump in the middle.
        
        - Constructor takes a copy of a sequence (list or tuple) of arbitrary values.
        - Sequence length must be greater than three, best if ten or more.
        - Values can be any Python object that can be passed around... string, int, list, function etc.
        - Performance scales by some tiny fraction of the length of the sequence. Method scaling may vary slightly.
        
        ```python
        from Fortuna import QuantumMonty
        
        
        quantum_monty = QuantumMonty(["Alpha", "Beta", "Delta", "Eta", "Gamma", "Kappa", "Zeta"])
        
        # Each of the following methods will return a random value from the sequence.
        quantum_monty.mostly_front()    # Mostly from the front of the list (geometric descending)
        quantum_monty.mostly_middle()   # Mostly from the middle of the list (geometric pyramid)
        quantum_monty.mostly_back()     # Mostly from the back of the list (geometric ascending)
        quantum_monty.mostly_first()    # Mostly from the very front of the list (stretched gaussian descending)
        quantum_monty.mostly_center()   # Mostly from the very center of the list (stretched gaussian bell curve)
        quantum_monty.mostly_last()     # Mostly from the very back of the list (stretched gaussian ascending)
        quantum_monty.quantum_monty()   # Quantum Monty Algorithm. Overlapping probability waves.
        quantum_monty.mostly_flat()     # Uniform flat distribution (see Fortuna.random_value)
        quantum_monty.mostly_cycle()    # Cycled uniform flat distribution (see RandomCycle)
        
        # Each of the methods can return a list of values as follows:
        quantum_monty.mostly_cycle(n_samples=10)    # Returns a list of 10 random samples.
        ```
        
        ### Table & Dictionary Wrappers
        #### Weighted Choice: Custom Rarity
        Two strategies for selecting random values from a sequence where rarity counts. Both produce a custom distribution of values based on the weights of the values. Up to 10x faster than random.choices()
        
        - Constructor takes a copy of a sequence of weighted value pairs... `[(weight, value), ... ]`
        - Automatically optimizes the sequence for correctness and optimal call performance for large data sets.
        - The sequence must not be empty, and each pair must have a weight and a value.
        - Weights must be integers. A future release may allow weights to be floats.
        - Values can be any Python object that can be passed around... string, int, list, function etc.
        - Weighted Values should be unique, pass non_unique=True during instantiation to bypass this check.
        As a result: non-unique values will have their probabilities logically accumulated.
        Relative Weights are summed, Cumulative Weights are over-lapped, but the effect is the same.
        - Performance scales by some fraction of the length of the sequence.
        
        The following examples produce equivalent distributions with comparable performance.
        The choice to use one strategy over the other is purely about which one suits you or your data best. Relative weights are easier to understand at a glance. However, many RPG Treasure Tables map rather nicely to a cumulative weighted strategy.
        
        ##### Cumulative Weight Strategy
        _Note: Logic dictates Cumulative Weights must be unique!_
        
        ```python
        from Fortuna import CumulativeWeightedChoice
        
        
        cumulative_weighted_choice = CumulativeWeightedChoice((
            (7, "Apple"),
            (11, "Banana"),
            (13, "Cherry"),
            (23, "Grape"),
            (26, "Lime"),
            (30, "Orange"),
        ))
        
        cumulative_weighted_choice()  # returns a weighted random value
        cumulative_weighted_choice(n_samples=10)  # returns a list of 10 weighted random values
        ```
        
        ##### Relative Weight Strategy
        
        ```python
        from Fortuna import RelativeWeightedChoice
        
        
        relative_weighted_choice = RelativeWeightedChoice((
            (7, "Apple"),
            (4, "Banana"),
            (2, "Cherry"),
            (10, "Grape"),
            (3, "Lime"),
            (4, "Orange"),
        ))
        
        relative_weighted_choice()  # returns a weighted random value
        relative_weighted_choice(n_samples=10)  # returns a list of 10 weighted random values
        ```
        
        #### FlexCat
        FlexCat wraps a dictionary of sequences. When the primary method is called it returns a random value from one of the sequences. It takes two optional keyword arguments to specify the algorithms used to make random selections.
        
        By default, FlexCat will use y_bias="front" and x_bias="cycle", this will make the top of the data structure geometrically more common than the bottom and cycle the sequences. This config is known as Top Cat, it produces a descending-step cycled distribution for the data. Many other combinations are possible (9 algorithms, 2 dimensions = 81 configs).
        
        FlexCat requires a dict with at least three sequences with at least 3 values each. Even though the total value limit is much higher, data sets with more than one million values are not recommended for all platforms.
        
        FlexCat generally works best if all sequences in a set are sufficiently large and close to the same size, this is not enforced. Values in a shorter sequence will naturally be more common, since probability balancing between categories is not considered. For example: in a flat/flat set where it might be expected that all values have equal probability (and they would, given sequences with equal length). However, values in a sequence half the size of the others in the set would have exactly double the probability of the other items. This effect scales with the size delta and affects all nine methods. Cross category balancing might be considered for a future release.

        ## Fortuna Development Log
        ##### Fortuna 0.20.7
        - Documentation updated for clarity.
        
        ##### Fortuna 0.20.6
        - Tests updated based on recent changes.
        
        ##### Fortuna 0.20.5, internal
        - Documentation updated based on recent changes.
        
        ##### Fortuna 0.20.4, internal
        - WeightedChoice (both types) can return a list of samples rather than just one,
        control the length of the list via the n_samples argument.
        
        ##### Fortuna 0.20.3, internal
        - RandomCycle can return a list of samples rather than just one,
        control the length of the list via the n_samples argument.
        
        ##### Fortuna 0.20.2, internal
        - QuantumMonty can return a list of samples rather than just one,
        control the length of the list via the n_samples argument.
        
        ##### Fortuna 0.20.1, internal
        - FlexCat can return a list of samples rather than just one,
        control the length of the list via the n_samples argument.
        
        ##### Fortuna 0.20.0, internal
        - FlexCat now accepts a standard dict as input. The ordered(ness) of dict is now part of the standard in Python 3.7.1. Previously FlexCat required an OrderedDict, now it accepts either and treats them the same.
        
        ##### Fortuna 0.19.7
        - Fixed bug in `.../fortuna_extras/fortuna_examples.py`.
        
        ##### Fortuna 0.19.6
        - Updated documentation formatting.
