Helper class for linearforms l(v), where v is a two form
![\[\displaystyle l(v)
= \int\limits_K f(x)v(x)\,dx
= \int\limits_{\hat{K}} f(F_K(\xi)) \hat{v}(\xi) d\xi\]](form_539.png)
Here, 
![$\hat{K} = [0,1]^2$](form_536.png)

Precomputes intermediate data for element matrix computation, this is
![\[f(F_K(\xi))\]](form_540.png)
which is stored for each quadrature point.
The class can be used as well for bilinear forms a(u,v) where u is a 0-form and v is a 2-form. One example is the bilinear form hp2Dedge::Graduv.
