Is your feature request related to a problem? Please describe.
In Python 3 default environment, using cFS-GroundSystem is a little tricky, since GroundSystem.py will use /usr/bin/env python for the Subsystem.

And the PyQt4 needs compile & build, it is hard to deploy in the virtual environment for it.

Describe the solution you'd like
Adding Python 3 compatibility for cFS-GroundSystem code.

Describe alternatives you've considered
By using 2to3, we can convert most of the code.

Only 2 parts need to concern:

• csv reader open file
  • Adding a middle layer of open, or detect version in each files
• zmq.socket.setsockopt
  • Does the subscription name need to support utf-8?

Additional context
No
