-added an automatic option to compute the SH-like support values (-f J option) on a given tree
 for each partition individually. If you invoke -f J with a partition file, the program will
 automatically also print out an additional tree file where the SH-like support values
 are displayed as branch labels in the form [s1,s2,...,sN] where s1...sN are the SH-like support values
 for each partition.
 At first glance this seems to be quite interesting because we already observed huge differences
 between the per-partition SH-like support values on a small test dataset.
