Drag and Drop Property Nodes

[smmarlow]

Allow the merging of Property Nodes using drag and drop editing. Dragging a property node onto another node would insert its terminals into the target node after the terminal onto which it is dropped.  The editor would highlight the terminal over which the programmer is hovering,  This behavior would only be exhibited for nodes of like objects.  For implicit nodes, the target (drop container) node would remain linked.

Would love to see this implemented for Bundle/Unbundle Cluster as well.

@jgcode Excellent idea, perhaps worthy of its own post.
