Detailed Description

template<unsigned DIM>
class QuadraturePointsGroup< DIM >

A simple class which takes in a mesh and a quadrature rule, and collects all the quadrature points in physical space (rather than in natural element coordinates) together in one data structure, for access.

In a distributed mesh, a set of quad points can still be accessed for a given element but then any missing data is marked with DOUBLE_UNSET
