Basic class for grid elements.
Class Galeri::grid::Element specifies the interface for a generic 1D, 2D or 3D grid element. This class is a semi-virtual class.
In Galeri/pfem, an element is defined as a geometric object, composed by vertices and components. The former are easy to define; the latter, instead, define the sub-entities of the element, and they are either segments (for 2D elements) or faces (for 3D elements).
The idea is that you can define an object by deriving this class, and set the correct number of vertices and components. You also have to decide the local ID of each of the components. Mixed components are perfectly legal. Since a component is nothing but an Element-derived class, you can recursively assemble components and create the object you need for your discretization.
This class is derived by Galeri::grid::Point, Galeri::grid::Segment, Galeri::grid::Triangle, Galeri::grid::Quad, Galeri::grid::Tet and Galeri::grid::Hex. New elements can be easily if required.
