Dragging and dropping modules expands irrelevant trees.

[theSloopJohnB]

If you drag a module from one engine to another, and you have a third collapsed tree in between, the collapsed tree will open when you drop the module.

See gif for details.

The repo is not storing the state ( open or closed) of the tree (VIEW). When we are dragging and dropping we are actually moving the nodes inside of the repo hierarchy array and then refreshing the tree (VIEW) . As the tree is "refreshed", it goes to the default state that is all nodes are open.
In order to add this functionality, we need to update CEF. The changes required will be:

• Add an extra property to the node (state open or close)
• Add code to update this property. This will be required in both of the main editor templates in CEF and also update in the editor in DCAF. The change will be add a event handle to the open and close event which then will store this information in the node.
• Update the RefreshEntireTreeWithGlyphManager.vi to call the closed method for all the nodes that were closed.

You will see similar behavior if you collapse the tree save it and load it. the close state is not preserved. In order to also add this functionality we will also need to save the state to the configuration file.
