PromptQueue Arguments are within the scope of the whole PromptQueue (how a command is represented in CommandPrompter). This type of argument can be placed on any of the prompts and is only needed to be placed once. If placed multiple times, CommandPrompter will still process the argument but will essentially be useless since the first appearance of the argument has already modified the whole PromptQueue.
Example:
The last prompt has an argument -exa
. This argument is called Post Command, which is essentially a command that will be called after the command is completed and dispatched. This is considered a prompt queue argument because it affects the whole prompt queue itself not just a single prompt.
