This implements a generic loop filter. Based on the analog PLL filters from Kaplan and Hegarty, with a bilinear (Tustin's) transform from s-plane to z-plane ( 1/s -> T/2 ( 1 + z^-1 )/( 1 - z^-1 ) ) Also added tests. Note the "truth" outputs were derived from an Octave implementation of the loop filter and Octave's builtin filter function
