			Essentially, this window aims at
			# providing a clear indication of the block structure of a model's equations and variables after reordering (read Piela's "Equation based modeling" from our publication list for some good background on that
			# showing exactly which variables and equations are present in a particular block, hopefully in a fairly intutiive/easy form,
			# giving some indication when there are variables at their upper/lower bounds, as that often gives a clue about the reason for divergence of the solver,
			# giving some indication when variables have a very small/large value relative to their nominal value, as that gives a clue when a variable might be badly scaled, reducing the effectiveness of the solver.

	This is an element of the PyGTK GUI that is intended to provide the user with additional solver-derived information regarding block structure of their models. At present it only really works with the [[NLA]] solvers.
