GGU-STABILITY: "Array" menu item

This menu item was previously explained in "Worked example 1: Data input with mouse". When entering system data using the mouse it may often be useful to lock on to certain array points.

Using this menu item you can define the array to be adopted. The default array colour is a light grey which does not overwhelm the graphics. If you would prefer to use a different colour, use the "Edit array colour" button. When the "Use array" check box is activated the defined array is used in conjunction with the subsequent menu items for mouse input of system data and for the definition of polygonal slip bodies.
