Simplify simulation of crystal roadmaps

[stestoll]

To simulate a series of crystal EPR spectra obtained from rotating a sample in small steps around an axis, it should be sufficient to use

rho = deg2rad(0:10:180);  % sample rotation angle
Exp.SampleFrame = deg2rad([0 45 0]);
Exp.SampleRotation = {rho,'x'};
Opt.separate = 'orientations';
pepper(Sys,Exp,Opt);
