Add common coder classes
Added coder classes as a common utility that can be used to encode and decode json data. Currently, it uses gson, but that can be changed. Separated the Coder interface from implementation. Used assertSame to compare references. Used numbers instead of strings so don't have to deal with escaping quotes in the test cases.
