I've been working on reduced basis problems, in particular the
reduced_basis ex3. To improve the accuracy of integration of an exponential
function, I want to set a high order for the Gaussian quadrature rule.
However, I found that the order of quadrature was decided by the FE_Type
object and I wonder if there is a way to allow the user to decide what
order rule is used for the integration. Thanks for your response.
