Routine Name:	listglobals

Description:	Lists currently defined GENESIS global variables and their
		current values.

Usage:		listglobals [global-symbols] -functions -variables

		-variables	only show variables (types int, float, str)
		-functions	only show functions (type function)
				
		(Uses last switch on line; if no switches, shows both
		functions and variables.  If the name is given, it shows
		only that global-symbol.)

Example:	genesis >  listglobals
		int             B_SPLINE_FILL = 0
		int             C_SPLINE_FILL = 1
		int             LINEAR_FILL = 2


Notes:		Four datatypes are recognized in listglobals:

			int
			float
			str
			function
