29 * \brief Class representing a single element of a mesh together with its bounding box.
30 * It gives access to the element's global number, type and bounding box and allows
31 * easy bounding box intersection tests between MeshElements and collections of MeshElement (MeshRegions)

66 * \brief Class defining an order for MeshElements based on their bounding boxes.
67 * The order defined between two elements is that between a given coordinate of
68 * their bounding boxes. For instance, if the order is based on YMIN, an element whose boxes
69 * has a smaller YMIN is sorted before one with a larger YMIN.
