Launcher for BEC GUI Applications
Application must be located in bec_widgets/applications ;
in order for the launcher to find the application, it has to be put in
a subdirectory with the same name as the main Python module:
/bec_widgets/applications
├── alignment
│ └── alignment_1d
│ └── alignment_1d.py
├── other_app
└── other_app.py
The tree above would contain 2 applications, alignment_1d and other_app.
The Python module for the application must have `if __name__ == "__main__":`

""" This custom class is a thin wrapper around the SignalProxy class to allow signal calls to be blocked.
Unblocking the proxy needs to be done through the slot unblock_proxy. The most likely use case for this class is
when the callback function is potentially initiating a slower progress, i.e. requesting a data analysis routine to
analyse data. Requesting a new fit may lead to request piling up and an overall slow done of performance. This proxy
will allow you to decide by yourself when to unblock and execute the callback again."""
