Spectrum: To PowerCepstrum

A command to create a PowerCepstrum from every selected Spectrum.

## Mathematical procedure

The spectrum X(f) is transformed to a new spectrum X′(f), where Re(X′(f)) = ln (Re(X(f))2 + Im(X(f))2) and Im(X′(f)) = 0.

The new spectrum X′(f) is then transformed to a Sound x(t) by means of an inverse Fourier transform as is described in Spectrum: To Sound. The squares of the transformed values, x(t)2, are stored in the PowerCepstrum.
