Calculates and plots the group delay in a semilogx scale for a system created using tf. This includes to continuous time systems and s domain transfer functions.

For example
H = tf(1,[1 1]); %// 1st order low pass with cut off at 1 rad/sec
groupDelaytf(H)
This will plot the group delay of the filter specified in H.
