/*
	'title' is the name that will appear in the dynamic menu,
		and also the command that is used in command files.
	'callback' refers to a function prototyped like this:
		static int DO_Class_action (UiForm sendingForm, int narg, Stackel args, const char32 *sendingString, Interpreter interpreter, void *closure);
		this function should throw an exception if the command failed,
		and return 1 if the command was executed successfully;
		this function will be called by 'praat' when the user clicks a menu command,
		in which case 'sendingForm', 'args' and 'sendingString' and 'closure' will be NULL;
		it is also called by scripts,
		in which case 'args[1..n]' or 'sendingString' is the argument list (after the dots).
		When called by Ui (after UiForm_create), 'sendingForm' is the UiForm, and 'closure'
		is the closure you passed to UiForm_create (which may be an editor).

	The availability of the dynamic commands depends on
	the current selection: e.g., if the user has selected three objects
	of type Matrix and nothing else, the commands registered with
	praat_addAction (classMatrix, n, 0, 0, 0, 0, "xxx", "xxxx", x, DO_xxx) are visible,
	and those with n=0 or n=3 are executable (the buttons are sensitive)
	and, if chosen, performed on each of these three objects;
	if the user has selected one object of type Artword and one of type
	Speaker, the commands from praat_addAction (classArtword, 1, classSpeaker, 1, ...) are executable.
	You may want to restrict the availability to one object for commands that write objects to file,
	commands that present information in a dialog, or the Edit command.

	CHANNEL (name, initialString)
		the name is also the string displayed in the label.
	BOOLEAN (name, initialValue)
		the name is also the title of the check box;
		the initial value is 0 (off) or 1 (on).
	LABEL (name, initialLabelString)
		'name' is not shown but can still be used by the SETs
	TEXTFIELD (name, initialString)
		'name' is not shown but can still be used by the SETs
	RADIO (name, initialValue)
		the name is also the string displayed in the label;
		this should be followed by two or more RADIOBUTTONs.
		The initial value is between 1 and the number of radio buttons.
	RADIOBUTTON (name)
		the name is also the title of the button.
	OPTIONMENU (name, initialValue)
		the name is also the string displayed in the label;
		this should be followed by two or more OPTIONs.
		The initial value is between 1 and the number of options.
	OPTION (name)
		the name is also the title of the button.
	OK
		this statement is obligatory.
	SET_XXXXXX (name, value)
		sets the value of REAL..LIST.
	DO
	The order of the macros should be:
		FORM
		one or more from REAL..LIST
		OK
		zero or more SETs
		DO
		...
		END
	See Ui.h for more information.
	Between DO and END, you should return 0 if something is wrong;
	if everything is alright, you should trickle down to END; never return 1!
	E.g. NOT return praat_new1 (...); BUT if (! praat_new1 (...)) return 0;
	This is because END updates the selection if an object was created.
