> CASSANDRA-2474 and CASSANDRA-3647 add the ability to transpose wide rows differently,
for efficiency and functionality secondary index api needs to be altered to allow composite
> I think this will require the IndexManager api to have a maybeIndex(ByteBuffer column)
method that SS can call and implement a PerRowSecondaryIndex per column, break the composite
into parts and index specific bits, also including the base rowkey.
> Then a search against a TRANSPOSED row or DOCUMENT will be possible.
