Title: Code Clean up.

Document if operations do not support doubles.
Fixed bugs:
- AsArray was not working with Ints. Also added AsArrayDouble.
- SurfacePointCalculations (Hillshade,Aspect,Slope) were not checking
for NoData correctly.
- Double versions of Zonal operations (Sum,Min,Max) were not dealing
with doubles properly.
Random documentation and formatting.

Closes #336
