Title: Fix regression affecting Linear Programming problems from ASU

Check to see what kind of Fraction to create in LinearProgramming.pl -- MathObjects Fraction or regular Fraction

This fixes a regression reported for the old style linear programming problems written at ASU as reported by John Jones

A decision needs
to be made as to whether to continue to support old style Fractions in this file.
By adding a few commands to the MathObjects Fractions we could have it imitate the behavior of the old style fraction.
This might be a better permanent fix.
