/** \brief Widget for displaying a grid on the graph.
 *
 * This class is a widget accessible from the interface of Tulip Software.
 * It is used to display a grid with some options. 
 *
 * You can, first, choose which type of cell you'll have :
 *  - Subdivisions cells are computed by taking the whole length of each axis of the graph, andby dividing them.
 *  - Sized cells are directly computed with the size you indicate.
 * 
 * Other options are available :
 * 
 *  - Display Dimensions : Allows the user to choose on which dimensions the grid will be displayed.
