I'm working on a PR that will extend how this handles types to fully embrace how Postgres handles types (namely, the existing behavior differs for Date, Time & ActiveSupport::TimeWithZone objects).

This was prompted by a gem I'm writing that will add in support for PG Multiranges in ActiveRecord, utilizing your gem as the in Rails data structure. Ultimately, I'd like to add this support directly into Rails itself, but, that's a ways off.

I have some other thoughts for small changes I'd like to make that I'll put into another PR (I think the initializer could accept an option to assume the input ranges are already sorted).

What do you think @khiav223577 ?
