With this commit, we do two things:

-  replace "hess_vec" with a simpler call of  "hessian" which
   calls internally "hess_vec".

- use "hessian2" by default instead of "hessian". "hessian2" calls
  internally "hess_mat" which is faster than "hessian/hess_vec".
  If the user encounters probems with the new "hessian2" driver, a
  boolean "useHessian2" can be set to false in the constructor.

Whitespaces only: Adjust indentation for commit 403dc032 (Add try{}catch{} around the energy calculation and the solve() call inside the trustregion solver)

In case an excpetion is thrown in either of these two calls, the trustregion solver will not accept the step and continue with a reduced radius

cleanup: remove/add includes

SumEnergy: Allow more than two local energies

Fix: TrustRegionSolver: use blocked matrices for fufem scalar basis assembler

See merge request agnumpde/dune-elasticity!31

valgrind complained here and it is right: in the internal loop of the
assembler we loop over localMatrix.N() and M(). Since dune-functions
uses flat matrices for the localMatrix the number of dof's is dim-times
too large for a powerBasis. In order to spare a double implementation of
the local assembler only for powerBasis, we can simply convert it in the
lambda. valgrind is now happy here.

NeumannEnergy: use std::function instead of Dune::VirtualFunction

See merge request agnumpde/dune-elasticity!32

We also use std::shared_ptr's instead of C-pointers.

Move deprecated warnings to member variables

See merge request agnumpde/dune-elasticity!33

Store a vector of local energies and sum the energy over all entries.

A method to add single energies is implemented.

Otherwise they get triggert even if the deprecated classes are not used.
Maybe not the best solution, but it will be removed soon anyway.

Migrate from dune-fufem to dune-functions bases

See merge request agnumpde/dune-elasticity!18

- local energies and assemblers depend now on the localView, instead of the element and the localFiniteElement
- the basis is now assumed to be a powerBasis (dune-functions compatible)
- this features flat element vector and matrix types and simplifies the implementation
- all affected classes are now in the Dune::Elasticity namespace

- for backwards compatibility, old implementation are kept in the "Dune" namespace and deprecated messages are placed
- the TrustRegionSolver is also capable of the new powerBasis

- TODO: dune-parmg is still hardwired to scalar basis types, therefore usage is not possible with the new basis

Whitespace cleanup

LocalDensity: use `ctype` for `x` entries

See merge request agnumpde/dune-elasticity!28

Give LocalIntegralEnergy a virtual destructor

See merge request agnumpde/dune-elasticity!27

It has other virtual methods, and therefore needs a
virtual destructor, too.

Remove an unused type

See merge request agnumpde/dune-elasticity!26

Replace local energies by local densities

See merge request agnumpde/dune-elasticity!24

 - wrap the densities by a generic Integral energy
 - this preserves all material properties
 - reduces redundant code

Dune does not support this anymore post version 2.7.

Otherwise distributed computations lead to a lot of cluttering.

Previously the tape number was hard-wired to '1'.  Using the
process number instead avoid two processes writing to the
same tape file.

In distributed situations, assembly has to happen on interior elements
only.  Select this partition type in a single location; previously
it was set several times in different places.
