> The Lucene FST data structure offers a compact and fast system for indexing Cassandra keys.  More keys may be loaded which in turn should seeks faster.
> * Update the IndexSummary class to make use of the Lucene FST, overriding the serialization mechanism.
> * Alter SSTableReader to make use of the FST seek mechanism
