Jiffy and JSX wrapper which returns a more standard Erlang map.
Optional data types can be passed as a second parameter, to provide seemless translation.

obj => #{ sub => atom } },
Erlang = #{ atom => value,
list => ["value"],
collection => [#{ key => one }, #{ key => two }],
string => "value",
bool => true,
integer => 1,
float => 1.0,
obj => #{ sub => value } },
Json = miffy:encode(Erlang, Types),
AtomStr = '{"string":"value","obj":{"sub":"value"},"list":[[118,97,108,117,101]],"integer":1,"float":1.0,"collection":[{"key":"two"},{"key":"one"}],"bool":true,"atom":"value"}',
Json = erlang:atom_to_binary(AtomStr, latin1), %% HACK dont do this to create strings
Erlang = miffy:decode(Json, Types).Miffy does NOT attempt to translate lists deeply, see unit tests for example behaviour.
However (as seen above) a collection type exists, which is a list containing objects of the same type.
