update.dendrogram - added options for: labels_colors, labels_cex, branches_color, hang, leaves_pch, leaves_cex, leaves_col
Fix "is.dendlist" to use inherits instead of class
`labels_colors<-` is more robust (for cases with partiel attr in nodePar). Also moved to using is.dendrogram more.
update.dendrogram added: branches_color, branches_k_color,      branches_col, branches_lwd, branches_lty, clear_branches, clear_leaves
assign_values_to_branches_edgePar - value can now be different than 1 (it now also has a recycle option for the value)
plotHclustColors - first import into the package
Rename plotHclustColors to color_bars - and made it work with dendrograms
color_bars - make sure to keep and reset the options
color_bars - adding more parameters. Made sure it can now be placed on top of a plot(dend).
colored_bars - added docs :)
tanglegram - preserve and restore previous par options (will no longer have a tiny plot in the left corner, when using a simple plot after tanglegram)
update.dendrogram - added .Rd docs :)
Added tests for update.dendrogram!
Minor doc changes
