*
* \ingroup FunctionSpaceBasesImplementations
*
* \note This only works for certain grids. The following restrictions hold
* - If k is no larger than 2, then the grids can have any dimension
* - If k is larger than 3 then the grid must be two-dimensional
* - If k is 3, then the grid can be 3d *if* it is a simplex grid
*
* All arguments passed to the constructor will be forwarded to the constructor
* of PQkNodeFactory.
*
* \tparam GV The GridView that the space is defined on
* \tparam k The order of the basis
