Dune-functions changes

Any version of dune-functions is supposed to be compatible with the corresponding version of the Dune core modules.

Release 2.10

• The module dune-uggrid is now officially a hard dependency of dune-functions.
• Added a constructor for LocalViewWrapper from a LocalView object and added accessor to base class for python bindings.
• The class Polynomial now allows to explicitly specify the used coefficient container. Supported containers are std::vector (default, as before), std::array, std::tuple, and std::integer_sequence. Class template argument deduction allows to deduce the scalar type from homogeneous containers. The scalar type can be explicitly specified to be different with the makePolynomial() helper function, while the coefficients container type is still deduced.
• Make AnalyticGridViewFunction copyable
• The method operator() of the class DiscreteGlobalBasisFunction has been implemented. It evaluates a piecewise function on a grid at a point given in global coordinates. As this evaluation requires finding the element that the evaluation point is in, it can be very slow.
• Reimplement HasStaticSize in terms by checking Hybrid::size()
• Add utility StaticSizeOrZero that defaults to the integral_constant<size_t,0> in case the container does only have dynamic size.
• Add global coordinate evaluation for CompositeGridFunction
• Add new global basis function based on refined Lagrange local-functions. The pre-basis is called template <typename GV, int k, typename R=double> class RefinedLagrangePreBasis and a corresponding pre-basis-factory refinedLagrange<k,R=double>() with k=[1|2] currently implemented.
• All basis implementations are now copyable and assignable
• Add mixin class LeafPreBasisMixin and make available the mixin class LeafPreBasisMapperMixin to simplify writing of new pre-bases.
• Add a dynamic power basis with a runtime exponent that can be constructed with the factory power(<sub-basis>, k) or power(<sub-basis>, k, <index-merging>).
• Add mixin class LFEPreBasisMixin to create leaf pre-bases based on a local finite-element and a layout.
• The class LeafPreBasisMapperMixIn is renamed into LeafPreBasisMapperMixin.
• Add data structures for container descriptors in namespace Dune::Functions::ContainerDescriptors.
• Introduce a new member-function .containerDescriptor() for all pre-bases that return an instance of one of the container descriptors to represent a container that can be indexed by the multi-indices of that pre-basis.
• Container descriptor for power bases with blocked-interleaved index-merging-strategy added.

Python

• The Nédélec and Raviart-Thomas function space bases are now accessible via the Python interface.

Deprecations and removals

• The class DefaultNodeToRangeMap and the corresponding header functionspacebases/defaultnodetorangemap.hh have been deprecated. This has been replaced as default by HierarchicNodeToRangeMap for some time.
• The BasisBuilder namespace is deprecated and will be removed after the 2.10 release. Use BasisFactory instead.
• The headers common/callable.hh and common/functionfromcallable.hh providing adaptors the the removed VirtualFunction interface from dune-common have been removed.
• Remove deprecated DefaultLocalView::isBound(), use bound() instead.
• The class HierarchicalVectorWrapper and the corresponding header functionspacebases/hierarchicvectorwrapper.hh have been deprecated. Use istlVectorBackend() from backends/istlvectorbackend.hh instead.
• The class SizeInfo and the corresponding header functionspacebases/sizeinfo.hh have been deprecated. One now can directly use vectorBackend.resize(globalBasis) instead of vectorBackend.resize(sizeInfo(globalBasis)).
• The deprecated header common/treedata.hh was removed.
• The deprecated header common/referencehelper.hh was removed. Use the corresponding header from dune-common instead.
