This commit *only* adds annotations. A note on typing of __init__: mypy requires init functions with no parameters to document a return type of None to be considered fully typed. In the case when there are input parameters, None may be omitted. Since __init__ may never return any value, it is preferred to omit the return annotation whenever possible.
