> Motivation:
> 1) Complete overhaul the API/implementation of "FieldCache" type things...
> a) eliminate global static map keyed on IndexReader (thus
> eliminating synch block between completley independent IndexReaders)
> b) allow more customization of cache management (ie: use
> expiration/replacement strategies, disk backed caches, etc)
> c) allow people to define custom cache data logic (ie: custom
> parsers, complex datatypes, etc... anything tied to a reader)
> d) allow people to inspect what's in a cache (list of CacheKeys) for
> an IndexReader so a new IndexReader can be likewise warmed.
> e) Lend support for smarter cache management if/when
> IndexReader.reopen is added (merging of cached data from subReaders).
> 2) Provide backwards compatibility to support existing FieldCache API with
> the new implementation, so there is no redundent caching as client code
> migrades to new API.
