Yamlet 0.0.2: add load routines to module scope, make opts optional

I had apparently not included any tests that didn't specify options to the Loader, so the very most basic example of how to load anything didn't work. Putting myself in the seat of a new user was very revealing. The Loader makes me pass some garbage options class I don't care about. There's no default `load` routine. There's no default `load_file` routine. It's just miserable to get started with this thing. So I fixed that.

Cuts version 0.0.2; will export to Pip.
