Subject: [PATCH] Make FEAssembler store a const reference of the basis
... rather than a copy. This allows to assemble with bases
that are not copyable, as for example the RaviartThomasBasis
See https://gitlab.dune-project.org/staging/dune-functions/-/issues/58

- Introduce class `LocalIntegralEnergy` to work with the densities
- Local energies and FE assemblers use now `dune-functions` power bases instead of scalar `dune-fufem` bases; the key element is the `LocalView` which contains the information for each element
- Introduce class `LocalHyperDualStiffness` and `hyperdual` to calculate gradient and hessian using hyper-dual numbers
+- The class `FEAssembler` now stores a `const` reference to the basis, rather than a value.
+ This allows to use the assembler with bases that are not copyable
+ (as, e.g., the `RaviartThomasBasis`, see [dune-functions issue 58](https://gitlab.dune-project.org/staging/dune-functions/-/issues/58)).
