def analysis.general_optics.trace_path	(	optics_system,
		beam
	)

tracks a beam through a composite_optic, and returns an optics_trace wrapper around the marks which were created.
        If an error is encountered which throws an exception, the exception is printed, and the partial trace returned.
        This makes it very easy to find a problem optic (e.g. a grating which is diffracting a beam away from the next item,
        or a mirror which isn't steered right).
