 New: The function GridGenerator::convert_hypercube_to_simplex_mesh allows to
-convert a given triangulation based on quadrilaterals (2D) or hexaedra (3D)
+convert a given triangulation based on quadrilaterals (2D) or hexahedra (3D)
 to a triangulation based on simplices or tetraedra, respectively. Thereby,
 material_IDs and boundary_IDs are inherited from the given triangulation.
