// This Fraction class allows extreme flexibility in working
// with fractions.  When a fraction is declared and the user
// and or client program implements a fraction with a negative
// denominator this class quickly distributes it to both the
// numinator and denominator to keep with what one would 
// normally do with Fractions in a Math class.  Operators are
// defined to work with extreme ease for the user of this class.
// A Reduce fraction is included to allow the user to use to
// simply the fraction that they are dealing with.
//
// Have fun with this class!
