Nonlinear phase between beats

[fernandoandreotti]

In order to make the model more realistic and make things more interesting for extraction methods, a nonlinear phase should be designed. In order to do so, some nonlinear phase - RR relationship is required.

Another solution may be to use the evolving Gaussian parameters AR-model, which seems easier to be implemented on our code. As in:
