* Cleanup of equality rewriting and no swapInsts for wanteds
- Removed code duplication
- Added comments
- Took out swapInsts for wanteds. With the recent extension to swapInsts
it does mess up error messages if applied to wanteds and i should not be
necessary.
NB: The code actually shrunk. Line increase is due to comments.
