Supplementary material has its own directory now

All the material for the supplementary material migrated now to a new
directory: supp. This includes all the figures for the supplementary
material previosly found at the img directory. The actual source file
is now supplementary.tex. This file contains some circos plots as
promised and all other figures and tables made by Israel. One of
Israels figures was made again by myself using R (code, output is all
in the supp directory!)
