ILADIAG
Purpose
This subroutine translated from a character string specifying if a
matrix has unit diagonal or not to the relevant BLAST-specified
integer constant.
ILADIAG returns an INTEGER. If ILADIAG < 0, then the input is not a
character indicating a unit or non-unit diagonal. Otherwise ILADIAG
returns the constant value corresponding to DIAG.
