Integer Class v.1

I created the associated methods for the integer class. I made the divide method return a bool that will be true if the number can be divided into an int. If it can, it will store the int in the pointer (int& ans) and return the value of the division that way instead of as the return type. This way we can test if the bool is true, if so the pointer will be set so we can use it's value. Otherwise, we want to return false and use the Rational class add method instead. Make sense to everyone?
