Aliases

This idea came up on mas-cli/mas#281 and I'm wondering if there is a simple way to create a 2nd command that is exactly like another without duplicating the 1st command. Has anyone come across this use case before?

Start by reviewing Commandant's command-handling API and the mas-cli/mas#281 use case referenced in the issue. Clarify whether aliases should be supported as a general API and what behavior must match the original command; the work is done when that scope and its acceptance criteria are agreed.
