PROBLEM STATEMENT
It is possible to assign a unique integer value to each irreducible fraction 
between 0 and 1. (This shows that there are a countable infinity of fractions.)
The usual way to number them is shown below

1/2  1/3  2/3  1/4  3/4  1/5  2/5  3/5  4/5  1/6  5/6  1/7  ...
 
Notice that 2/4, for example, does not get listed because it reduces to 1/2.
Given an irreducible fraction we want to find where it appears in the above
counting order, where 1/2 is counted as 1, 1/3 as 2, etc.

Create a class FracCount that contains a method position that is given the numerator
and denominator of an irreducible fraction between 0 and 1 and that returns its
position in the counting order.



DEFINITION
Class:FracCount
Method:position
Parameters:int, int
Returns:int
Method signature:int position(int numerator, int denominator)


CONSTRAINTS
-numerator will be between 1 and denominator - 1 inclusive.
-denominator will be between 2 and 1,000 inclusive.
-The greatest common divisor of numerator and denominator will be 1.


EXAMPLES

0)
1
2

Returns: 1



   1/2 is at position 1 in the counting order



1)
5
6

Returns: 11



   5/6 is at position 11 in the counting order


2)
999
1000

Returns: 304191
