/** \page commands Commands
To implement undo and redo functionality, every possible action
by the user for editing and manipulating the document is encapsulated
in a command (based on KCommand).
There is one command class (which will be instantiated) for every unique
action. You need to reimplement the execute() and unexecute() methods
of KCommand.
Each command is created from the user interface, and then added
to the command history (see Doc::commandHistory) using
Doc::addCommand method. Because the command is not immediately
executed, you also need to call the execute() method of that command.
This is an example of typical use of command:
\code
KCommand* command = new RenameSheetCommand( sheet, name );
doc->addCommand( command );
command->execute();
\endcode
Then whenever the user triggers an "undo", the corresponding
unexecute() method of the command is called by the undo action,
thereby reverting the previously executed command. Similar thing
happens for the "redo".
Alphabetical list of commands:
\li AddSheetCommand
\li DissociateCellCommand
\li MergeCellCommand
\li RemoveSheetCommand
\li RenameSheetCommand
