Simple OPC-UA GUI client.

Written using freeopcua python api and pyqt. Basic functionnalities are implemented including subscribing for data changes and events, write variable values listing attributes and references.

What works:

• connecting and disconnecting
• browsing with icons per node types
• showing attributes and references
• subscribing to variable
• make available on pip: sudo pip install freeopcua-client
• remember connections and show connection history
• subscribing to events
• write variable node values
• gui for certificates
• gui for encryption

TODO (listed after priority):

• detect lost connection and automatically reconnect
• gui for loging with certificate or user/password (can currently be done by writting them in uri)
