 * Class: mxLine

 * Constructs a new line shape.

 * Parameters:
 * 
 * bounds - <mxRectangle> that defines the bounds. This is stored in

 * stroke - String that defines the stroke color. Default is 'black'. This is
 * stored in <stroke>.
 * strokewidth - Optional integer that defines the stroke width. Default is
 * 1. This is stored in <strokewidth>.
