Editable text - If Max - Min > 1, then editable text boxes accept multiline input. If Max - Min <= 1, then editable text boxes accept only single line input.
For multiple line editable text or static text controls, line breaks occur between each row of the string matrix, and each cell of a cell array of strings. Vertical slash ('|') characters and \n characters are not interpreted as line breaks, and instead show up in the text displayed in the uicontrol.
