Detailed Description

Implements a PLL which locks to the input frequency and outputs an estimate of that frequency. Useful for FM Demod.

input: stream of complex; output: stream of floats

This PLL locks onto a [possibly noisy] reference carrier on the input and outputs an estimate of that frequency in radians per sample. All settings max_freq and min_freq are in terms of radians per sample, NOT HERTZ. Alpha is the phase gain (first order, units of radians per radian) and beta is the frequency gain (second order, units of radians per sample per radian)
