// The purpose of this program is to generate a table of multiplication
// given a specific denominator of a fraction. 
//
// This program has been constructed through multiple files. In 
// other words, there is a seperate file for the class definition,
// one for the members functions, and another for the driver of it.
//
//
// Table of Variables:
// -------------------
// num       = Numerator of the fraction (a) or (c) or result
// denom     = Denominator of the fraction (b) or (d) or result
// dummychar = Dummy Character that contains the fraction symbol
// fract1    = First Fraction Object for column header printing
// fract2    = Second Fraction Object for column header printing
// fract3    = Relult Fraction Object for column header printing
// fract4    = FirstFraction Object for row header printing
// fract5    = Second Fraction Object for row header printing
// fract6    = Result Fraction Object for row header printing
// fract7    = First Fraction Object for table body printing
// fract8    = Second Fraction Object for table body printing
// fract9    = Result Fraction Object for table body printing
// response  = Contains a Y or N depending if the user wants to 
//             continue calculating another set of fractions
// i         = Counter Variable for rows
// j         = Counter Variable for columns
// n         = Denominator entered by user for table generation
//
