Fiducials detection

Fiducial detection using the libfidtrack library from http://mtg.upf.edu/reactable/?software . Fiducials are very nifty patterns that use connectivity graphs as unique coding. This allows having any number of shapes, going away from the "black square" paradigm of other patterns (see ARToolkit). Detection returns 2D position and orientation plus an estimate of the pattern size (which can roughly be used to compute the distance from camera).

Nothing new really but very easy to add to your projects (no ARToolkit main loop integration etc) and very quick and robust.

Note: the tags disappear when they become too small, that's because they become smaller than the nominal search size..
