Read an OpenCV classifier stored as XML

[aldebaro]

One can find several already-trained classifiers in OpenCV (see opencv\build\etc\haarcascades). The issue here is to read them into Octave (highest priority, and secondarily Matlab). Octave has some support (see http://octave.sourceforge.net/io/function/xmlread.html ). After reading the XML, it should be converted to a data structure that can be manipulated.

Reference [8](see readme file) provides code to read an older version of the XML
