A series of immutable types for use in python projects.
ImmutableList - The ImmutableList type is a python type that allows you to instantiate a list once and then use the contents of that list. As this list is immutable, it can not be modified in any way.
Set - the Set type in python is mutable. Python's built in frozenset is the immutable version of the Set type. No additional types are needed.
Dict - the Dictionary type in python is mutable. Pythons built in namedtuple type is the immutable version of the dict type. No additional types are needed.
