Parameters
		float c11=0.   float c13=0.   float c33=0.   float c55=0.   float c66=0.   int color=7   float dash=0.0   bool disp=y [y/n] if n, give phase velocity instead of dispersion relation   float edash=0.1 elliptical approximation dash   bool ellipse=y [y/n] if use elliptic approximation   int fat=5   bool group=y [y/n] if n, give group slowness instead of group velocity   float groupscale=1. scales only the group stuff   float inc=0.5 increment of phi sub w in degrees   bool info=y [y/n] if print in small letters the elastic constants across the top   bool line=n [y/n] if draw lines to indicate some important angles. (Angles at which triplication "first" occurs, and angles at which pure P and Sv modes exist)   string log=   float norm=0.   string only= (Pdisp, SVdisp, SHdisp, P, SV, SH)   bool particle=n [y/n] if show particle motion directions   float phasescale=.5 scales only the phase stuff   string title=   float vrscale=1. scales everything by a factor
