External module function *dspindensity_coeff1* - used by *mcdisp*

In order to visualize spin density fluctuations
the external single ion module has to provide the transition
matrix elements of the spindensity coefficient operator
by a
vector , which is given by:
.

The format to be used is:

extern "C" int dspindensity_ceoff1(int & tn,double & T,Vector & Hxc,Vector & Hext,double * g_J,Vector & MODPAR,
char ** sipffilename,ComplexVector & aSlm1,int & xyz,float & maxE, ComplexMatrix & est)

The meaning of the symbols follows exactly that of function
*dm1* and therefore not explained here.
