Node - #activity#terminate

• For Xmind ChatTree, the first line of the node content must be "#activity#terminate", and then there is no need for other lines of content, such as:

  #activity#terminate

• For Python ChatTree, the first parameter of chattree.create_node() must be "#activity#terminate", and the second parameter dict is empty, such as:

  xxx_node = chattree.create_node("#activity#terminate", {})

• End the entire dialogue immediately (during the dialogue, if the user explicitly requests to end the dialogue, it will also end)
• The "TMC_book_flights" ChatTree example in "ChatTree Examples" contains this node
