Windows global hooks in pure Python
The implementation uses foreign function interface (FFI) provided by
standard Python module **ctypes** and inspired by pyHook, pyhooked and other
similar modules (the code was re-written from scratch). It tends to be
a superset of pyHook but in pure Python only so it doesn't require compilation.
Current set of hooks implemented:
* WH_MOUSE_LL
* WH_KEYBOARD_LL
More detailed documentation about Windows hooks can be found in MSDN:
https://msdn.microsoft.com/en-us/library/windows/desktop/ms632589.aspx
This module can be used as a stand alone or along with pywinauto.
The fork of this code (at some moment) was used in
standalone library pyhooked 0.8 maintained by Ethan Smith.
