Maya unload shelf

To remove a shelf in Autodesk Maya, you can use Maya's deleteShelf command. But this changes the original shelf file.
This script let's you simply unload a shelf, without changing the original shelf file.

place script in

C:\Program Files\Autodesk\Maya2019\scripts\others

or include in your scriptpath

call using mel script

unloadShelfTab("my_shelf_name");

• No confirm dialogue for easier use in scripting.
• Adapted from the deleteShelfTab function.
  To allow easy diff in case of future updates I simply commented out the changes in code. See diff
• Unloading a shelf won't be remembered in the next Maya session, if you auto load the shelf on startup (e.g. shelves in the shelves folder). The unloadShelfTab command is meant to be used together with loadNewShelf command, so you can load and unload shelves in a maya session
