Support Curl Computations

[philipc2]

Add support for computing the finite-volume curl at each vertices using a vector on the cell edges.

An MPAS specific example can be found here

@philipc2 I can tackle this if you want, it looks fun. Could you give me some information on what a finite-volume curl is? Are there any papers I could read about what it is?

We are most likely going to have this as part of our upcoming SIParCS project. I can let you know if we end up doing something else though .
