			At first view the interface is daunting but try not to dispair. Some people, us at least, think it has a logic. It is divided into a set of panels. The largest is the plotting window on the right. Just to the left is a column of buttons, tick boxes, drop-down lists and buttons that control the plotting window.<br><br>
			Top left is a panel for loading and saving projects. (one of the most used is Reset. If you have made a programming mistake in the interaction function it is necessary to Reset the GUI).<br><br>
			Below this is a Panel for selecting tools. These buttons select what Panel will be visible below, e.g. Mesh Editor, or Factors (for adding morphogens), etc.<br><br>
			At the bottom left are controls for running the model: Step, run for a specified number of steps, for a specified (model) time, run to a certain area (e.g. 2 times starting area). Above the Run Panel is a Panel for electing to Edit the interaction function, call the interaction function without actually growing.<br><br>
			There are also controls on the Menu bar. At this stage you might consider that the GUI has the wrong sized font. It can be changed through the Menu:Misc:GUI format control.
