Detailed Description

class FEComputeData hides arbitrary data to be passed to and from children of FEBase through the FEInterface::compute_data() method.

This enables the efficient computation of data on the finite element level, while maintaining library integrity.

With special finite elements disabled (like infinite elements), this class wraps the return values of all shape functions from FEInterface::shape() in a std::vector<Number>.
With infinite elements enabled, this class returns a vector of physically correct shape functions, both for finite and infinite elements.
