Added finalResults fixture for use when inner joins are set up.
Improved notes on optimizations in partialJoin with a dicussion of a batching strategy which could be used to provide an O(C) memory usage guarantee for difficult cross-adapter join cases (namely subqueries and multistep joins with large child datasets)
Added inner join, and refactored join logic in the process to make it more modular.
Tests+fixture for inner join.
