Setting up :
------------

- Include the model in your model file.

	<model> 
		<path>Aircraft/Instruments-3d/chronograph/chronograph.xml</path>
		<offsets> 
			<x-m>xxx</x-m>
			<y-m>xxx</y-m>
			<z-m>xxx</z-m>
		</offsets>
	</model>


- Declare chronograph.nas in your foo-set.xml file. Write something like:
	</nasal>
		<chronograph>
			<file>Aircraft/foo/Nasal/chronograph.nas</file>
		</chronograph>
	</nasal>


- Open chronograph.nas and uncomment chrono_loop() and the following settimer()
if update_chrono() has to be launched standalone.
Otherwise launch foo_chronograph.update_chrono() from a centralized loop which
will save some CPU cycles.
See chronograph.nas line 48.

That's it.
