Add support for versioning

[doneill]

The EarthRanger JSONForms schema spec is adding a version 2 to support a user friendly web based form building experience. This issue needs to refactor the source directory structure to add support for version 2 while maintaining backward compatibility with version 1 of the schema spec.

Action:

• Organize the source code with a versioned architecture pattern

Expectation:

• Backward compatibility
  • v1 schemas continue working without any changes
• Clear separation
  • Each version is isolated
• Future Proof
  • Easy to add future versions
• Testing
  -Each version can be tested independently

Fixed with #20
