Change notification support for FS.
This module defines a standard interface for FS subclasses that support change
notification callbacks. It also offers some WrapFS subclasses that can
notification callbacks. It also offers some WrapFS subclasses that can
simulate such an ability on top of an ordinary FS object.
An FS object that wants to be "watchable" must provide the following methods:
* ``add_watcher(callback,path="/",events=None,recursive=True)``
Request that the given callback be executed in response to changes
Request that the given callback be executed in response to changes

This method returns a Watcher object.
