SingleInstance(port)

Construct this when your app starts, to initiate communication with any duplicates. If it is the only instance, this will start a background server, and pass any args to mySingleInstance.OnArg(arg). If there is an existing instance, this will pass sys.argv[1:] to it.

It is your responsibility to check if mySingleInstance.duplicate, and quit.

example:

>>> import sys, qubx.singleInstance
>>> mySingleInstance = qubx.singleInstance.SingleInstance(MY_APPS_HIGH_PORT_NUMBER)
>>> if mySingleInstance.duplicate:
...     sys.exit(0)
>>> print sys.argv[1:]
