I added a template class called Shift which gets rid of the warnings
about negative shifts. It does this by specializing the cases for each
type. If the count would have been negative the shift is not done. I
avoided using partial specialisation, since some compilers don't support
it and used a macro to do it instead.

I'll try and get rid of the signed/unsigned warnings.
