Simple OPC-UA GUI client.

Written using freeopcua python api and pyqt. This is alpha quality with strange window resizing happening. Pull requests / Patches are welcome!

What works:

• Connecting and disconnecting
• showing attributes and references
• subscribing to variable
• make available on pip: sudo pip install freeopcua-client

TODO (listed after priority):

• remember connections and show connection history
• detect lost connection and automatically reconnect
• more human friendly attributes and refs display
• subscribing to events
• installer for windows

NOT PLANNED:

• support for certificates (need to be implemented in python-opcua)
• support for encryption (need to be implemented in python-opcua)
