playdough 1.0.0

The premise of this gem is that consumers of your API need versioning and different shapes of your resources. Without proper thought into versioning and shaping, your codebase can quickly resolve into a redundant and confusing state. This gem tries to solve that problem by allowing the API owner to use simple conventions -- Accept headers and ActiveModelSerializer namespacing -- to achieve controller reuse by controllers delegating resource versioning and shaping to the serializer level.
