How to use the Mapping Mesh Toolbox
The GUI figure is divided into three main areas: grid creation, subdomain creation, and axes.
The grid creation area must be used first. All subdomain vertex locations will snap to grid points.
After creating a grid, you are able to draw a subdomain, alter its vertex locations,
and choose the number of divisions along each side.
All drawing and visualization of the mesh takes place in the axes.
