Lightweight JSON processor and AST.

Safely deserialize JSON decoded Strings to Dart Types.

A JSON decoding library that actually decodes nested lists. 

**No more dynamic mapping!**

````dart

const example = """

{

  "aRidiculousListOfLists": [ [ [ [ "Lugia", "Ho-Oh" ], [ "Pikachu!" ] ] ] ]

}""";

final decoded = example.jsonDecode;

final myArray = decoded.array("aRidiculousListOfLists");

expect(myArray.data[0][0][0][0], "Lugia");

expect(myArray.data[0][0][0][1], "Ho-Oh");

````
