// This program uses the same class as was used in Lab Exercise
// 7 and 8. The purpose of this program is to allow a user to 
// enter a number of fractions through the keyboard. These 
// fractional numbers, will then be added together to obtain a total 
// for all the fractions entered by the user. The total is then 
// divided by the number of fractions entered by the user to 
// calculate the Average of these sets of fractions. 
//
// 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
// total     = Object of type fraction that holds total of fractions
// avg       = Object of type fraction that holds average of fractions
// fract[n]  = N-th Array Element from Array fract
// response  = Contains a Y or N depending if the user wants to 
//             continue calculating another set of fractions
// i         = Counter Variable for loop
// n         = Number of fractions entered by user to program
