The distribution is calculated as follows:
101 bins are formed between zero and maximum rmsd in equal separation
(by calculating the largest value by 100 to create the separation). Each
rmsd value is put into the right bin and the counter for that bin is
increased by 1. The total number of counts is the size of half a matrix.
If the maximal rmsd is 10.0 and a certain comparison yield rmsd=0.13 the
value of the second bin in increased by 1.
