Resolves #55

[x] write the agent
[x] rewrite SSTable.query
[x] load all the indices from disk on startup
[x] invoke on memtable.flush, saving the newly created index into main memory
[x] on compaction, evict dead entries and make sure all new entries are present in the agent
[x] don't bother with fallback to disk.
