             LinkableImportPanel

Modal dialog for selecting a Linkable node in the script.

The following class creates a modal dialog with one UI element: an enum of nodes that derive from the LinkableI class. (The LinkableI interface allows us to easily query and import 2D data from a variety of sources, particularly the Tracker node.) The user then selects their source node to import the data from. Once Ok'ed, the code below creates a new user track for each LinkableInfo object returned in the node.linkableKnobs() function with an XY co-ordinate, and then copies each animation curve entry.
