encodeAction takes a string and encodes it to JSON of the following format

-- for example the user gives a custom type DefInit as input
encodeAction <| Debug.toString DefInit 
-- { "type": "DefInit", "payload":"null" }

NOTE : only custom types can be encoded, others will result in an error JSON -- for example if I try to encode Int 5 encodeAction <| Debug.toString 5 -- it will result in -- { "type": "ActionTypeError", "payload": "Please change Msg type to Custom Data type in Elm app" }

encodeModel uses Analytics.Parser's encodeFlat function

NOTE : If an error is encountered during parsing following JSON is returned -- { "type": "ModelParseError", "value": "ModelParseError" <RawString> }
