// .NAME vtk3DGridSource - Create a 3D polygonal grid
// .SECTION Description
//
// vtk3DGridSource creates a 3D grid centered at origin. The grid is represented
// with lines. It is possible to specify the length, width, 
// and height of the grid independently. Also the number of cubes in the grid
// can be specified.
