 * Archiving extravaganza:
 *
 * We archive mesh and pde through a pointer to an abstract class. All the potential concrete
 * classes need to be included here, so they are registered with boost. If not, boost won't be
 * able to find the archiving methods of the concrete class and will throw the following
 * exception:
 *
 *       terminate called after throwing an instance of 'boost::archive::archive_exception'
 *       what():  unregistered class
 *
 * No member variable is defined to be of any of these clases, removing them won't
 * produce any compiler error. The exception above will occur at runtime.
 *
 * This might not be even necessary in certain cases, if the file is included implicitely by another header file
 * or by the test itself. It's safer though.
