Brett Smith a2ee9c73fe ranges: Start module.
The ledger report wants to use this functionality, so make it available in a
higher-level module.

I took the opportunity to clean up a lot of the surrounding type
declarations. It is less flexible, since it relies on the static list of
types in RangeT, but I don't think the other method actually worked at all
except by cheating with generic Any.
