Initial project setup
Project structure is now a thing, also the metadata engine has been written using leveldb
Updating .gitignore to include .swp files
make sure to actually unpickle data stored in iterables
Add a has_key method to MetaEngine to determine if a key is present in leveldb
added zip_safe=false to setup.py
Fixed LibreDB.get_peers, it didn't return anything before now
Added option arg to specify db name to MetaEngine __init__
Added an initial pass at the document storage engine, it uses an instance of MetaEngine to store index information and stores the actual pdfs on the file system in subdirectories
