introduces tests for BuddiesModel (this also introduces the need for a new collection called test)
moves the work of connection to the db from the model to a separate mongo utility, this allows for us to not have to connect to the db every time a model method is called AND allows us to use this utility in testing
refactors the seeder tool and moved the logic to a utility and the actual seeding to script file
Closes #57
