/**
* \class LoadElement
* \brief Virtual element load base class.
*
* This load class defines an external load that acts on elements in a system.
* The vector with pointers to elements defines, on which elements
* the load acts. The derived load classes should provide members, that allow the
* Element's class Fe() member function to uniquely transform the load into nodal loads.
* No special requirements are enforced on those members.
*
* Ultimately, when assembling the right hand side of the master equation (master force vector)
* the Element's Fe() member function is called with the pointer to the LoadElement class that is
* prescribed on that element. Fe() function shuld dynamically cast this pointer to specific
* load class, which it can handle and return the element's force vector.
