Protein sort

The goal of this merge request is to order the proteins based on triangle properties (Height, Mean, Width). This way when the phenotype is computed, the order of the proteins will always be the same instead of depending of the locus in the genome.

The major difference with this update will be that mutations that only modifies the order of proteins in the genome wont modify the phenotype anymore. The measures of robustness should be more precise with this update.

The modifications come with a Test. This test fail with current aevol6 but the modification done with this merge request make it succeed.
