Port skymap to pytest
I did most of the pep8, futurize and pytest work already. There are still problems with division.
fred3m can you review this please? It's a dependency of pipe_tasks. Nothing really complicated. The majority of the changes are tweaks to get testing working properly.
Looks good to merge.
Thanks. Merged. jmatt you need to ask frossie whether this work should be attached to an epic.
