Added shape and bb support.

[gknisely]

ported only the needed tiles logic from valhalla. Updated db logic t…o use thread_local. Added logic to obtain a list of geojson tiles located on disk. Added logic to intersect those tiles with a BB in order to obtain the features from them. Added support for BB query. Added logic to support including geometry or not.

TODO: allow support of just BB or IDs in the query.
