A StringMorph that constantly tries to show the current data from the target object. When sent #step, it shows what the target objects has (target perform: getSelector). When edited (with shift-click), it writes back to the target.

floatPrecision = 1. to round to integer.
floatPrecision = .1 to round to 1 decimal place, etc.

Even when ((target == nil) or: [getSelector == nil]), the user would still like to edit the string with shift-click.

	floatPrecision Answer the floatPrecision to use: 1.0 -> show whole number 0.1 -> show one digit of precision .01 -> show two digits of precision etc. Initialize the floatPrecision to 1 if it is not already defined

	maximumWidth Answer the maximum width that the receiver can have. A nil value means no maximum, and for practical purposes results in a value of 99999 here temporarily, for help in future debugging
	minimumWidth Answer the minimum width that the receiver can have. A nonzero value here keeps the receiver from degenerating into something that cannot ever be seen or touched again! Obeyed by fitContents.

	putOnBackground Place the receiver, formerly private to its card, onto the shared background. If the receiver needs data carried on its behalf by the card, such data will be represented on every card.

	veryDeepInner: Copy all of my instance variables. Some need to be not copied at all, but shared.

	editing	top
	acceptContents The message is sent when the user hits enter or Cmd-S. Accept the current contents and end editing. This default implementation does nothing.
	addCustomMenuItems:hand: Add morph-specific items to the given menu which was invoked by the given hand. This method provides is invoked both from the halo-menu and from the control-menu regimes.
	doneWithEdits If in a SyntaxMorph, shrink min width after editing
	handlerForMouseDown: Answer an object to field the mouseDown event provided, or nil if none
	handlesMouseDown: Do I want to receive mouseDown events (mouseDown:, mouseMove:, mouseUp:)?
	lostFocusWithoutAccepting The message is sent when the user, having been in an editing episode on the receiver, changes the keyboard focus -- typically by clicking on some editable text somewhere else -- without having accepted the current edits.
	mouseDown: The mouse went down over the receiver. If appropriate, launch a mini-editor so that the user can commence text-editing here

	stepping	top
	step Do some periodic activity. Use startStepping/stopStepping to start and stop getting sent this message. The time between steps is specified by this morph's answer to the stepTime message. The generic version dispatches control to the player, if any. The nasty circumlocation about owner's transformation is necessitated by the flexing problem that the player remains in the properties dictionary both of the flex and the real morph. In the current architecture, only the top renderer's pointer to the player should actually be honored for the purpose of firing.
	stepTime Answer the desired time between steps in milliseconds. This default implementation requests that the 'step' method be called once every second.
