WIP cfn2py enhanced with cfn2pyclass. Creates tree structure of python classes for manageable json creation

[sbraverman]

WIP - DO NOT MERGE -

Currently: cfn2py prints to console a large python file. This file is difficult to manage/enhance programmatically.

GOAL

Create a more manageable system that can be version controlled with easing future changes in mind

WORK DONE SO FAR

• cfn2pyclass enhances cfn2py - instead of printing the python code to console, the python code is saved into individual python classes within a regional tree structure (this will be argument input by user).
• jinja2 templating is used for file creation
• base object (not included) handles iterating through the created region/aws_instance file structure and creates the json file
• enhanced the securitygroups (ingress and egress)

WORK STILL TO DO

• better way to import necessary modules
• Parameterize necessary user inputs
• Allow users to change all IP's upon json creation
• Pep8
• Fix some bugs....
