the triple product will be used in mpfa methods to determine whether or not
three connection vectors form a right hand basis inside a sub control volume

The subcontrol volume class is identical for the different cellcentered methods.
This commit renames the CCTpfaSubcontolVolume to a CCSubcontrolVolume and moves
the header to the corresponding location. The property defaults are changed accordingly.

There are a restriction of the global vector obtained
by a localView call and then bound to an element.

The global object can create an empty temporary local object that
can be bound to an element/stencil. This is closer to the
current dumux-stable implementation and still allows to switch
between global caching (for smaller problems where memory is not an issue)
and local caching (variables are precomputed for each element assemble temporarily)

Works for cc and box (in 2d). Box needs some performance improvement,
probably when creating the box geometries. But also other parts
might be possbile to optimize.

We iterate over all scvs of a fvElementGeometry like this
for (const auto& scv : scvs(fvGeometry))
This is closer to the way we speak "For each scv in all scvs of the fvElementGeometry do..."
and analogously to how we iterate over elements of a gridView.

A new folder named discretization is introduced on the /dumux level.
In this folder there are all the geometry classes as well as vol vars, flux var cache
and physical laws (darcy, fick etc), since they could be possibly reused in decoupled
models and are not restricted to implicit models. NOTE: The fluxvariables and the flux
variables cache are still in the folder /porousmediumflow/implicit/. It is to be discussed
whether or not they should be moved into the discretization folder as well.

the flux var cache vector is now set specifically for box and cc methods

this method is now specialized by the boxlocaljacobian and
the cclocaljacobian

the boundary treatment is now performed after all the interior
fluxes have been calculated. This corresponds more to the previous
implementation and is assumend to be more correct for mixed BCs.

This class has not been used since many commits ago. It was time
to delete it.

The flux var cache is now specialized for the box and cc methods
and furthermore permits the binding of an element prior to flux calculations
in order to recycle data later in the flux calculations when the global
caching is disabled.

the local jacobian now also gets the global residual passed as
argument for the assemble routine and stores the values in it.
