LeadLag:
-------------------------------------------------------------------------------
Create a lead or lag with the appropriate phase characteristics
in the form
tau1 s + 1
K(s) = Kdc ----------
tau2 s + 1
Given the desired maximum phase magnitude (±90°) and frequency
-------------------------------------------------------------------------------
Form:
