Started adding some geometric manipulation methods to the misc file
- These might be better in their own file
moved transformations to Utilities, and dropped the leading _
- I think we should adopt these for our own coordinate manipulations, but they require knowing a little bit more about geometry than most want to...so perhaps we can wrap the main ones in our methods...something to think about
Moved the thermalconduction and stokesflow tests we ran with Marc Secannel to /tests
Fixed up importing of transformations.py throughout
