Use KEY_AND_ROW by default
Allows grouping with tuples, but needs to be cleaned up substantially + tested
Fixed some bugs, but still more bugs + style issues left

Merge branch 'tuplesByDefault' into keyAndRowTuples
Most tests passing now, should just need to fix Boolean/WrappingByteSource errors
Added support for Boolean and WrappingByteSource
Cleanup
