WIP: First attempt to move Interceptor creation behind the Record and a Protocol
WIP: Capture the implementation as a multimethod as well - for prosperity
Simplify interceptors by isolating the core functionality; rename namespaces
There are no standalone InterceptorFns - you must now use a list within route definition. ie: function calls only
All interceptor conversions should be controlled by the core interceptor protocol
All 'definterceptorfn's are now 'defn's and need to be called in interceptor vectors, you can no longer pass them as bare symbols - that is reserved for 'handler's only
Update the minor version number - interceptor API updates are a breaking change
Remove the dead multimethod interceptor API
