Detailed Description

The OngoingCommandDispatcher class.

A basic, type-unsafe dispatcher for a commands that have continuous edition capabilities.

That is, it is useful when you want to have a command that has a long initialization but a very fast update. For instance, moving an object : initializing the command is (relatively) long so we don't want to create a new one at every mouse movement.
Instead, such commands have an update() function with the same arguments than the used constructor.
This dispatcher will call the correct method of the given command whether we're initializing it for the first time, or modifying the existing command.
