int main	(	int	argc,

	)

First, we set the command line arguments and the configuration filename, and we define the options that can be used in them (using QwOptions).

Now we setup the message logging facilities with the requested loglevels.

Fill the search paths for the parameter files

Load the tracking detectors from file
