Insert Bundle Unbundle

Inserts a Bundle/Unbundle pair for the selected wires. The selected wires are bundled into one cluster in top-to-bottom order, unbundled again, and reconnected to their original source and sink terminals, so the data flow is unchanged.

Limits: a selected wire may have only one downstream terminal (no branches). A wire with branches is reported as an error and the diagram is left unchanged.

Inputs:

• QD Launch VI Ref - the VI QuickDrop was launched from; its block diagram selection is used (normal use).
• Diagnostic VI Path - when not empty, the VI at that path is opened instead and every wire on its diagram is processed, then the VI is saved (testing and batch use).

Outputs:

• error out - reports an error when the selection is not made of wires, holds fewer than two wires, or contains branches.
• changes made? - whether the diagram was modified.

The undo transaction is managed by the caller (the QuickDrop plugin template).
