/**
* Generates a static type corresponding with this Bindings object. The generated type is a nesting of Gosu structure types.
* This nesting of types is intended to be placed in a .gs file as a top-level structure, or embedded as an inner type.
*
* A structure type is a direct mapping of property members to name/value pairs in a Bindings. A property has the same name as the key and follows these rules:
*
* - If the type of the value is a "simple" type, such as a String or Integer, the type of the property matches the simple type exactly
*
- Otherwise, if the value is a Bindings type, the property type is that of a child structure with the same name as the property and recursively follows these rules
*
- Otherwise, if the value is a List, the property is a List parameterized with the component type where the component type is the structural union inferred from the values of the List recursively following these rules for each value
