Local Data Storage

[bbengfort]

Create some methodology for local data storage of the JSON meta data for the files.

Thoughts:

• Use LevelDB where the key is the signature and the value is the JSON metadata
• Use a MongoDB server to store?

Questions:

• What about duplicates? E.g. the same file is stored on two different paths?

Created simple LevelDB storage handler similar to the DSS project handler.
