Provides global signal dispatching services.
 
Slightly modified version for vrml and OpenGLContext
packages.  Modifications eliminate the cast to string
for the signal objects, which allows for non-string
signal values.

Classes
		BoundMethodWeakref Exception DispatcherError _Any   class BoundMethodWeakref     BoundMethodWeakref class.     Methods defined here: __call__(self) Return a strong reference to the bound method. __init__(self, boundMethod) Return a weak-reference-like instance for a bound method. __repr__(self) Return the closest representation.   class DispatcherError(Exception)       Methods defined here: __init__(self, args=None) Methods inherited from Exception: __getitem__(...) __str__(...)   class _Any

Functions
		_call(receiver, **kwds) Call receiver with only arguments it can accept. _cleanupConnections(senderkey, signal) Delete any empty signals for senderkey. Delete senderkey if empty. _removeReceiver(receiver) Remove receiver from connections. _removeSender(senderkey) Remove senderkey from connections. connect(receiver, signal=<wxoo.dispatcher._Any instance at 0x015E53A0>, sender=<wxoo.dispatcher._Any instance at 0x015E53A0>, weak=1) Connect receiver to sender for signal.   If sender is Any, receiver will receive signal from any sender. If signal is Any, receiver will receive any signal from sender. If sender is None, receiver will receive signal from anonymous. If signal is Any and sender is None, receiver will receive any          signal from anonymous. If signal is Any and sender is Any, receiver will receive any          signal from any sender. If weak is true, weak references will be used. disconnect(receiver, signal=<wxoo.dispatcher._Any instance at 0x015E53A0>, sender=<wxoo.dispatcher._Any instance at 0x015E53A0>, weak=1) Disconnect receiver from sender for signal.   Disconnecting is not required. The use of disconnect is the same as for connect, only in reverse. Think of it as undoing a previous connection. safeRef(object) Return a *safe* weak reference to a callable object. send(signal, sender=None, **kwds) Send signal from sender to all connected receivers.   Return a list of tuple pairs [(receiver, response), ... ]. If sender is None, signal is sent anonymously.
