RPC results are difficult to use

[CurleySamuel]

Currently very little structure to the returned data. We literally take all the cells that HBase spits out and spit it back at the user as a relatively arbitrary list of embedded lists. _flatten_cells was a small helper function I wrote to test the number of cells returned to make writing tests easier.

We should offer various functions to parse the returned results. Parse everything into a dictionary by key/column/column-family? Embed lists by rows (all cells in the same row will be in the same sublist)? Even offer "getRowFromResult" or similar functions?
