Detailed Description

Factory to create StackOperators and help from StackOperatorCreators.

This class is simple for a reason: if you want to change available commands, create a factory for each situation and provide it when relevant.

Note

When creating StackOperators, the first added creator that can make a StackOperator wins and terminates. There is no ambiguity or resolution done.
