Rename from "add" to "set"!
Rename 2 file names from add->set (set.dendrogram.R and tests-set.dendrogram.R)
order.hclust (new function) - Ordering of the Leaves in a hclust Dendrogram
rect.dendrogram - started working on the function. (we start with rect.hclust, and move from there)
`rect.dendrogram` - just like `rect.hclust`, plus: works for dendrograms, passes `...` to rect for lwd lty etc, now has an horiz parameter!
identify.dendrogram - function and docs added. (it might be a bit buggy...)
