Added a placeholder for "as.dendrogram.randomForest"
Fixing .Rd indentation.

      * inst/doc/2013-09-05_Boston-useR
      * vignettes/figure
README.md - invitation to get credit for using dendextend.
exported prune_leaf
leaf_Colors - fix example (added "dend").
Added to .Rbuildignore "vignettes/"
(we'll deal with this later...)
S3methods no longer seem to be exported (due to something in roxygen2), I chose to update the tests accordingly.
      * cutree.hclust -> dendextend:::cutree.hclust
      * cutree.dendrogram -> dendextend:::cutree.dendrogram
cut_lower_fun acts diffirently on dendextendRcpp vs old dendextend, so I updated the tests to reflect that.
changed functions names:
      * trim -> prune
      * unroot -> unbranch
cutree.dendrogram - turned into S3 (no longer exported)
