Patch for reference element

 


I have added and modified some of the FIAT code so that one can choose between using the FIAT and the UFC reference element.

In particular, a module reference.py has been added which contains the reference element specific mappings. Also, shapes.py have been generalized somewhat and I have added the necessary fixes to expansions.py and moved things around a bit there.

A repository with the changes can be found at

Rob, would you like to see if you think it is ok and pull if you do?
