def launch_mia():
"""Actual launch of the mia software.
Overload the sys.excepthook handler with the _my_excepthook private
function. Check if the software is already opened in another instance.
If not, the list of opened projects is cleared. Checks if saved projects
known in the mia software still exist, and updates if necessary.
Instantiates a 'project' object that handles projects and their
associated database anf finally launch of the mia's GUI.
**Contains: Private function:**
- *_my_excepthook(etype, evalue, tback)*
Log all uncaught exceptions in non-interactive mode.
All python exceptions are handled by function, stored in
sys.excepthook. By overloading the sys.excepthook handler with
_my_excepthook function, this last function is called whenever
there is a unhandled exception (so one that exits the interpreter).
We take advantage of it to clean up mia software before closing.
:Parameters:
- :etype: exception class
- :evalue: exception instance
- :tback: traceback object
**Contains: Private function:**
- *_clean_up()*
Cleans up the mia software during "normal" closing.
Make a clean up of the opened projects just before exiting
mia.
- *_verify_saved_projects()*
Verify if the projects saved in saved_projects.yml are still
on the disk.
:Returns: the list of the deleted projects
