Description

Implementation of command invocation on the Session interface.

This is the actual service implementation and runs within Session subsystem. It is managed by the DispatcherLoop, which also starts the Session Loop Thread. Moreover, for actually perform any command, the command operation needs to be defined somewhere statically, as a function operating on the current session, plus an state capturing and UNDO function. And the concrete arguments of the command functor must be suitably bound.
