Chunks

[orianac]

Three changes:

• Building out some checks in the chunks schema.
• Adding a check that the input is actually a da, since if it's a dataset the chunk routines will fail for the wrong reason.
• Remove the return of the da at the end since I think we just want it to continue without returning anything.

@jhamman Take a look- added logic to cover chunks being True, False or a dict, and added a few more tests to cover some corner cases.
