/** @file test-dummy-commands.hpp
 ** Some dummy command functions used for building unit test cases. 
 ** Any of these functions comes in triples of operation function, undo state
 ** capturing function and und function. They are placed into a nested test
 ** namespace, together with some global variables used as a backdoor to
 ** verify the effect of calling these functions.

 ** @see command-use1-test.cpp
