[PD] a sort of a tempo tracker [pd challenge]

I just saw a very impressive thing by Ed Large (a neuro-science guy from
UCONN). He models neuron oscillations with coupled nonlinear equations
and with this he gets really nice spikes at the pulse tempo even with
signals that don't have any onsets on the beat.
He said the model will be available in a month or so and the paper is
still under review. The other thing is that there is a training layer
(also neuro-model motivated) that you have to warm the thing up with,
but my impression is that you only have to do this once and then it is
ready to go. It's worth keeping an eye on for beat tracking solutions.
