Deprecated:

The LexiographicSearch for bandwidth optimization is not in use. Can it be removed?

		logical	Optimize,
		logical	UseOptimized,
		character(len=*)	Equation
	)

Subroutine for reordering variables for bandwidth and/or gaussian elimination fillin optimization. Also computes node to element connections (which implies node to node connections, and thus the global matrix structure).
