* Finite elements in one dimension need only set the @p{restriction}
* and @p{prolongation} matrices. The constructor of this class in one
* dimension zero. Changing this behaviour in derived classes is
* generally not a reasonable idea and you risk getting into trouble.

* In addition to the fields already present in 1D, a constraint
* matrix is needed, if the finite element has node values located on
* constrained. Only one level of indirection is allowed. It is not known
* at the time of this writing whether this is a constraint itself.
