v.1.0.1

Update readme.md

First release

Includes Matlab code for weighted comb filters based on kernel convolution.
Kernel shape can be convex or concave, delayed, symmetric or causal.
Weight functions can be uniform, linear, exponential, gaussian or empirically based on periodic autocorrelation.
Additional implemented filters are a causal complex filter (essentially a kernel version of a discrete Fourier filter) and periodic principal component removal.
