Project 2  FixedPoint Number Class

This program is Project 2 in Exploring C++, by Ray Lischner (Apress).
Your task for Project 2 is to implement a simple fixedpoint number class. The class represents fixedpoint numbers using an integer type. The number of places after the decimal point is a fixed constant, four. For example, represent the number 3.1415 as the integer 31415 and 3.14 as 31400. You must overload the arithmetic, comparison, and I/O operators to maintain the fixedpoint fiction.
