Expose dict values as list

[liamhuber]

Just adds to_list() methods to DotDict and DataIO so the dictionaries can be case to value lists. The order is explicitly not guaranteed, but it winds up being the order items are added to the underlying dict.

As requested in #38.

Closes #40.

Riiight. Because the two tests each had the same name, only one of them was getting run and it wasn't this one. This actually does break expectations -- trying to assign input to input should raise an error.
