Code Issues Proposed changes

Minor fixes to Mongo DB client

Browse Source 
* Two method calls define dictionary as arg in param signature. Set arg to None, and check value in body.
  if arg is none, then set value to empty dictionary.
* 'Filter' argument shadows actual python call. Changed variable name to minimize damage (best practices),
      but did not change signature in case keyword arg invocation exists somewhere in code base.
* __init__() call did not call parent's init (BaseClient)
* Fixed pep8 violations found by flake in data_interfaces.py
