-added the ability to parse trees with branch-labels (not node labels) as displayed
 in the RAxML_bipartitionsBranchLabels.RUN_ID files in the tree rooting option (-f I option)
 and display them on the rooted tree.
 Note that, the branch label (representing the support) at the root will be duplicated,
 that is, if I insert the root at an inner branch with a support of say 68, a branch label
 with support 68 will be displayed on each of the two branches descending from the root.
