Dependencies

The only dependency added is the org.json.simple JSON parser.

Design

See details in ticket above, examples include

1. format : {version}/{area}/{api}/{action}
2. example: v1/accounts/signup/login

Notes

1. Also removed use of roles from kiit.common.auth
2. There are a lot of changes due to files moved around, and package changes and tests.

Pending

There is a separate issue regarding custom parameter types loaded from the request as part of deserialization. This is going to be handled in a separate ticket.

Tests

1. Tests updated for loading/looking up routes
