Time Range

Found the need to be able to create a time range in list form.

Ended up writing a bunch of new types, functions, and some prisms, so here we are.

Suggestions for the API, types, extra granularity or other such things is encouraged and appreciated. This is very much a WIP in library as it was created for a very specific need, but I thought others might find it useful.
