quadrature implementation based on the standard DUNE quadratures
Though a factory by name, this is a quadrature implementation using the standard quadratures from DUNE grid to generate a list of quadrature points.

Adds an integration point to the list.
This method allows derived classes to add integration points to the list. This mehtod should only be used within the constructor of the derived class.

Adds a point-weight pair to the quadrature.
This method allows derived classes to add quadrature points (and their respective weights) to the list. This mehtod should only be used within the constructor of the derived class.

obtain the identifier of the integration point list
The identifier of an integration point list must be globally unique. Even integration point lists for different dimensions must have different identifiers.

obtain order of the integration point list
The order of a quadrature is the maximal polynomial degree that is guaranteed to be integrated exactly by the quadrature.
In case of an integration point list, the definition of this value is left to the implementor.
Implements Dune::Fem::IntegrationPointListImp< FieldImp, dim >.

obtain coordinates of i-th integration point
This method returns a reference to the coordinates of the i-th integration point for 0 <= i < nop(). The integration point is given in local coordinates, i.e., coordinates with respect to the reference element.
[in] | i | number of the integration point, 0 <= i < nop() |

obtain weight of i-th integration point
This method returns the weight of the i-th integration point for 0 <= i < nop() within the quadrature.
[in] | i | number of the integration point, 0 <= i < nop() |
