[Optimoz] gesture recognition with a hidden markov model

[Aaron Lenfestey]

First results!  Just a few minutes ago.

I gave it a short input of this crappy data:

 0, 17.2, 34.4, 5.7, -17.2, -17.2, -28.6, 11.5,  0, -22.9, -40.1,
-57.3, -63.0, -85.9, -34.4, -28.6, -51.6, -57.3, -40.1, -34.4

which represents the angular displacements (in degrees,
counterclockwise from R) of a sequence of pointer movements.  the
model correctly identified it as:

^^RRRRRRRR3333333$$$  ---> R3

notice the old recognizer would probably have broken on the 34.4,
definitly on the -86.  anyway, i'll iron out the code some more and
try to construct some more detailed experiments.
