New autocalibration technique to generate points in line (use case:
underground tunnels). The handling of the
positioning.generate-reference-points has changed to be able to use
several autocalibration methods simultaneously.
The code for the EvAAL output was slightly updated in 2012 for the 2nd
contest. Although OwlPS doesn't handle sub-areas of interest, it was
indeed compatible with the 2012 evaluation system.
Like in the other modules, we get rid of the old use of "access point".
This has user-visible changes, especially in the configuration (the name
of a few options has been changed).
