Detailed Description

EvalState with caching support. Historically this was part of EvalState, but it was split out to make maintenance easier. This could've been just a pair of EvalState and the cache map, but doing so would currently hide the rather strong connection between EvalState and these caches. At some future time the cache interface should be changed to hide its EvalState.
