	/* How to share implementation of methods between multiple derived classes
	without putting it into the base class. Using the curiously recurring template
	pattern.

	"""This script demonstrates the overhead of using SyncManager vs Value.

	Output:

	Method calls on AutoProxy seem to be two orders of magnitude slower.
