The status object is not being initialised on import, to allow controlled setup upon start up.

The status object is being initialised and setup before execution of the main relax class.

Fixes for the status object by renaming __init__() to setup() and calling it only once.

The object was not acting as a singleton because of the presence of __init__(). This is now fixed.

The Mf.bug_14941_local_tm_global_selection system test now prints out some status info.

This is to test the status container.

Model-free analysis can only be started if PDB file was selected.

Error message is popping up if model-free calculation is started without pdb file specified.

The settings for parameter files are stored in integers. The GUI converts them and passes integers back to the relax data store.

In addition, the settings dialog is craeted in the relax_gui.py script.

relaxGUI job is killed upon exiting the program.

This is to completely kill running threads, which can't be controlled under Python. The error was detected by Edward d'Auvergne reported at https://gna.org/bugs/index.php?17317.

All of the auto-analyses now lock relax's execution while they are in operation.

An execution lock has been added to the status object.

This allows parts of relax to prevent others from running, which is especially useful in certain
UIs. A special Exec_lock class object has been created to simulate a proper threading.Lock object,
but with certain additional features.
