Monkey patch all annotated functions

Recursively search for all annotated functions declared within the scope of the current project and monkey patch them so that they enforce types.

>>> import foo

>>> # type not enforced yet
>>> foo.simple_type_hinted_function(2)

>>> from enforce_types import enforce_all
>>> enforce_all()

>>> # type enforced now, exception
>>> foo.simple_type_hinted_function(2)
