A flag for the DurationToLength class that forces the calculated length to
be even.
Bugfix: A sweep and silence length that added up to an odd value could
crash the RecordTransferFunction program.
Some classes to model a system with Hermite polynoms of Laguerre functions.
This was suggested in the book "The Volterra and Wiener theories of
nonlinear systems" by Martin Schetzen.

The source code here is neither sufficiently documented, nor is it covered
by unit tests. It also contains print statements to show the progress of
the often lengthy calculations.
Little changes in the status messges
Some changes to the LaguerreHermite model
Auralization of a loudspeaker that is modeled by its (nonlinear) Thiele-Small
parameters
Add a warning that the helper.differentiate function is faulty
Calculate the derivatives for the Thiele-Small parameter auralisation in
the frequency domain
