[test] to verify mcq.drop.uncorrelated.peptides. For this release if there is still proteins with one peptide they will be dropped by mcq.select.2pepbyprot function.

[mcq.drop.uncorrelated.pep.new] debug. attention, dans l'ancienne version, le pep de ref n'est pas inclu dans pepok. Par csq, on peut avoir des prot avec 1 seul pep après avoir fait tourner la fonction

[mcq.drop.uncorrelated.peptides] get back to precedent function mcq.drop.uncorrelated.peptides to finish unitary tests

[test] suppress test for mcq_drop_uncorrelated_peptides from test_mcq_select2pepbyprot.R and add file for mcq_drop_uncorrelated_peptides test

[test] rename test_get_compar.R => test_mcq_get_compar.R and add test from test/test_mcq_getcompar.R(suppressed) and results files Nov2016

[mcq.plot.cluster] add control of nbclust, [test] rename test_cluster.R => test_mcq_plot_cluster.R, results file with data Dec2014
