PURPOSE - THIS ROUTINE PERFORMS SYMBOLIC FACTORIZATION ON A PERMUTED LINEAR SYSTEM AND IT ALSO SETS UP THE COMPRESSED DATA STRUCTURE FOR THE SYSTEM.

INPUT PARAMETERS - NEQNS - NUMBER OF EQUATIONS. (XADJ, ADJNCY) - THE ADJACENCY STRUCTURE. (PERM, INVP) - THE PERMUTATION VECTOR AND ITS INVERSE.

UPDATED PARAMETERS - MAXSUB - SIZE OF THE SUBSCRIPT ARRAY NZSUB. ON RETURN, IT CONTAINS THE NUMBER OF SUBSCRIPTS USED

OUTPUT PARAMETERS - XLNZ - INDEX INTO THE NONZERO STORAGE VECTOR LNZ. (XNZSUB, NZSUB) - THE COMPRESSED SUBSCRIPT VECTORS. MAXLNZ - THE NUMBER OF NONZEROS FOUND.
