The metadata of a form is commonly used to store a quadrature rule; it would be better support giving a quadrature rule to a form. To do this we need to:

[ ] Add DefaultQuadrature subclass of this
[ ] Add quadrature_rule property to Form
[ ] Optionally allow Form to take a quadrature rule when it is created (with default value DefaultQuadrature)
