This where the figures and tables for the section on scale were done. A
bit confusing because there is stuff here that didn't work out.

The R code to produce proposal.eps is scale.R.

The files to produce the conditional mean functional are

scale_mu.cpp
scale_mu.sh
sdf.ctrl_mu.000
sdf.parm_mu.000    -> sdf.parm.000
control.dat_for_mu -> control.dat
