			* ''What is the event model of JSXGraph?''



			The event model of JSXGraph is the following:
			- An onmousemove event in the HTML element containing the JSXGraph construction and
			- an onmousup event of the whole HTML document
			trigger the method JXG.Board.update() .

			JXG.Board.update() calls the update() method of each element (points, lines, texts, ...) of the board.

			Thus, by dragging a point, onmousemove of the HTML element containing
			the construction is triggered. This triggers the call of JXG.Board.update(),
			which calls all update() methods of each element.

			The update() method of each element computes the new position of the element
			and its layout (strokeColor, strokeWidth). This update() method can use
			the position of other elements, see the Lissajous example.
			The Hilbert example is somewhat more complicated:
			It overwrites the (previously empty) method updateDataArray() of a curve of curevType "plot".
			In that method the new data points are computed depending on one slider.
			Then, with
			this.dataX = ...;
			this.dataY = ...;
			they are handed to the curve tight before they are plotted.


			Other special cases:
			- In order to speed up things the update() of (all) elements can be
			prevented by calling
			board.suspendUpdate();
			until the call of
			board.unsuspendUpdate();

			- JSXGraph updates ALL JXG.Boards in an HTML document. So
			elements of one board can depend from elements in another board.
