/** \page shapes Shapes
 *
 * Shapes are present for denoting a specific region of the simulation domain.
 * There are four primitive types present:
 *  - Sphere
 *  - Ellipsoid
 *  - Cuboid
 *  - Cylinder
 *
 * Note that all may be modified (shrink/grow, rotate, morph) via an arbitrary
 * matrix.
 *
 * The shapes are for the moment only used within \ref descriptors to specify
 * a specific subset of atoms, here that reside in a certain region of the
 * simulation domain.
 *
 * \todo There is a certain relation between Tesselation and Shape. Hence, later
 * Tesselation shall itself be a Shape, i.e. that describes a certain region in
 * space, here via a tesselated mesh.
 *
 * Again, Shapes can be joined via boolean operators:
 * - add
 * - or
 * - not
 *
 * And thus are a very powerful concept.
 *
 * E.g. a shape can be used like this
 * \code
 * Cuboid(Vector(0,0,0), Vector(2,2,2)) && !Sphere(Vector(1,1,1), 1.)
 * \endcode
 * which would match any object within the cuboid from (0,0,0) to (2,2,2)
 * that is not in the unit sphere at (1,1,1).
