Update README to better show off the framework

The current README is bare and doesn't demonstrate what the framework is capable of. Update the README to include at least the following:

• Badges to reflect project status and information
• A brief description of the framework's use case
• Getting started describing an overview of how to use the framework
• Instructions on how to get to the CONTRIBUTING.md to learn how to contribute to the framework
• Better graphics and images of the framework in action
• License information
