				init_membrane.c

Purpose:
	Initialize the membrane thickness and  some other data required
	to draw two planes which are used to represent the membrane. It
	is done for all proteins,  though makes sense only for membrane
	proteins.

Input:
	(1) Pointer to MolComplexS structure, with macromolecular data.
	(2) Pointer to ConfigS structure, with configuration data.
	(3) Pointer to GUIS structure, with GUI data.

Output:
	(1) Plane colors and  some other data set for  two planes which
	    are used to represent the membrane.
	(2) Return value.

Return value:
	(1) Positive always (trivial).
