MS_sphere

MS_SPHERE - Plot a spherical plot of phasevels/anisotropy from a set of
             elastic constants.
// Part of MSAT - The Matlab Seismic Anisotropy Toolkit //
Given an elasticity matrix and density, produce spherical figures showing
    the P- or S-wave anisotrpy.
MS_sphere(CC,rh,mode,...)
Usage:
    MS_sphere(CC,rh,mode)
        Mode can be 'p'(-wave), 's'(-wave), 's1' (fast s-wave) or 's2'
        (slow s-wave).
MS_sphere(CC,rh,mode,...)
     Further arguments are EVALed. Parameters that can be (re)set
     are:
       cmap = jet(64) ; colourmap
       icmapflip = 1 ; reverse the sense of the colourscale
       FSWTickLength=0.08 ; Fast shear wave vector length
       plotlabels = 1 ;
       plotaxes = 1 ;
       nofig = 0 ; suppress the figure command, so plot can be sub-plotted
       nocbar = 0 ; suppress the colorbar
       cax = NaN ; colour axis, define to use - default is auto
       dirs = [] ; directions of interest, this should be a vector of azi,
                      inc pairs, e.g., [az1 in1 az2 in2 az3 in3 az4 in4]
       dlen = 1.5 ; length of doi vectors
