Implement IComparer

[twiglet]

Comparator
Interface IComparer from C# is not translated correctly. The generated Java class looks as follows:
public class PostProfileComparer extends IComparer
{
public int Compare( PostProfile x, PostProfile y) throws Exception {
return y.getScore().Compare(x.getScore());
}

}
but interface IComparer is not defined, and also method Compare is not defined on type int (the result type of method getScore()).

We haven't yet implemented the IComparer class. I will look into that.
When we do then y.GetScore() should be automatically cast to an
Integer before we call the Compare method.

Or alternatively use the < > == comparison on the ints directly. Simply returning y.getScore() - x.getScore() would be a simple solution,
Unfortunately this is not safe regarding int overflows.  I have translated it to
  return y.getScore() == x.getScore() ? 0 : (y.getScore() > x.getScore() ? 1 : -1)
