Fixes to make_uh and formatting changes.

- Major speed improvements in make_uh due to the use of np.convolve rather than pure python convolution as was previously implemented.
- Some pep8 fixes but there are still some issues.
Changes to allow for routing on the same grid as the target domain.
i.e. if REMAP = False and AGGREGATE = False.
Add C convolution routine for speedup

-Also changes to structure of ring and unit hydrographs.  Changes are internal and are backward compatable.
-Fixed bug in agg_tsteps logic
