---------------------------------------------

Jake, I think we can do a polymorphic base class.  Then create two different kinds of index interfaces, row level and column level.  The SecondaryIndexManager will then do an instance of.

> For index types that index an entire row (like lucene) we need to change the api to handle one instance of the index per ColumnFamily.  This can be done by adding a isRowLevelIndex() method.  When the index manager sees this it will add all columns of the same index class to the same index instance.  and on search it will send the entire row to the class vs updating each column.
