Color dend's labels according to sub-clusters
This function is for dendrogram and hclust objects. This function colors tree's labels.
The groups will be defined by a call to cutree
using the k or h parameters.
If col is a color vector with a different length than the number of clusters (k) - then a recycled color vector will be used.

col |
Function or vector of Colors. By default it tries to use
rainbow_hcl from the |

logical (default from dendextend_options("warn") is FALSE). Set if warning are to be issued, it is safer to keep this at TRUE, but for keeping the noise down, the default is FALSE. (in case h/k/labels are not supplied, or if col is too short) |

a tree object of class dendrogram.
This function is in the style of color_branches, and
based on labels_colors.
