0.0.4

Added:

• Implemented db.search().

• Schemas contain key telling whoosh if a field should be stored.

• Preloader indexes artifacts.

• Script to index artifacts not currently in index.

• New REST API for searching the database.

Changed:

• When creating a whoosh index, an indexname is supplied so multiple indexes can exist in the same directory.

• When indexing document, ignore fields not present in schema rather than raise an error.

• Pulling updates to libcfgraph is now more robust, and should not require
  human intervention ever.

• New simple search for searching artifacts uses grep, head, and tail.

Removed:

• Removed Whoosh, as it is deprecated, so that we may start fresh!
