Title: Multiple selections

I implemented the ability to select multiple dendrogram structures using the three mouse buttons (on my mac, they correspond to "click", "option-click" and "control-click" for (1, 2, 3) respectively). Some of the internal variables are now dictionaries corresponding to the mouse Event identifiers.

I am pretty sure this works overall. Is this worth merging into master?
