/** @file command-def.hpp
 ** Actually defining a command and binding it to execution parameters.
 ** While the header command.hpp contains everything needed for executing and
 ** commands and referring to them, this more heavy-weight header is needed when
 ** \em defining the concrete operations to be encapsulated into a command. To
 ** create a command, you need to provide three functors (for the actual operation,
 ** the undo operation and for capturing undo state prior to invoking the operation).
 ** Besides, you provide a \em binding, thus creating a closue out of these three
 ** function objects and a set of actual parameters. This closure effectively is 
 ** the command, which in a last step can be either dispatched, stored or 
 ** invoked immediately.

 ** @see Command
 ** @see Mutation
 ** @see CommandClosure
 ** @see ProcDispatcher
 ** @see CommandBasic_test simple usage example
