/* PROGRAM: translate.c
** PURPOSE: Back-end formatter for AIM (Adaptive Image Manager) MOC output
**            - translates AIM MOC output into Matlab-compatible (x,y) pairs
**              for use with Matlab graphs
**            - can be used only with one MOC parameter specified at a time
** FILES:   iostream.h      : C++ I/O library
**          fstream.h       : C++ file library
**          string.h        : C++ string library
