LagrangeBase: Lagrange enumeration for triangle was wrong.
Checked with baseTest from poisson.cc

Lagrangebase for hexahedron and polynom order = 1 added.

Minor bug in gaussquadimp fixed.

There is a default implementation which uses the methods reset, operator ++
(int i) , and the * () operator of the implementation class.
For efficient implementations this methods should be overloaded.

methods global and local of AlbertGridElement checked.

[[Imported from SVN: r119]]

-DDIM=2 or 3,
-DDIM_OF_WORLD=2 or 3 >= DIM
-DEL_INDEX=1 (stands for save the element number on the elements,
              EL_INDEX=0 leeds to not saving the element number, but we
              need them)

If one of these option is forgotten an error is thrown.

Furthermore only the interface methods are public from now on, as it
should be.

I got was an internal compiler error. So I wait for gcc 3.4

[[Imported from SVN: r114]]

added some typedef for MemberType and enum for dimension to Vec and Mat in
matvec.hh

[[Imported from SVN: r113]]

Jacobian_inverse implementation revised and now nearly as fast as the
Albert implementation.

NeighborIterator revised and now we have a speedup.

LagrangeBase:

caching of basefunction values at quadrature points works for gradients
aswell now.

Tested with the implementation of Poisson equation and compared with an
Albert implementation of the same problem. :-) we are close.

In lagrangebase.hh there are the implementaions of lagrange Base functions
for linear basis for triangles and quadrilaterals and a lagrange base set
for arbitrary lagrange base functions. Furthermore there is the
implementation of the lagrange discrete function space.

  future)

dynamic value. FastQuadrature is the template implementation and Quadrature
the dynamic version.

gaussquadimp.hh .cc  is the GaussQuadrature implemented by Peter
but now with order as template parameter but the same functionality.
This was needed for the new implementation.

quadlqh.hh provides gauss quadrature with the new interface for lines,
quadrilaterlas and hexahedrons, i.e. its an interface between Peters
GaussQuadrature and the other stuff.

To everybody:
Please inform the others, if you change features. It's easy to ask, if the
person to kick sith right beside you, but that isn't allways the case.

angelegt. Hier muss man noch klären, ob das reicht, oder ob man dynamisch
die Ordnung der Quadrature festlegen möchte.

FastBase cached jetzt die Werte an den QuadraturePunkten, so dass die
Auswertung der Basisfunktionen nur einmal pro Quadratur vorgenommen werden
muss.

expect to be a Dofstorage, i.e. provides a local dof iterator and a global
dof iterator.

DofStorageDefault provides two extra featrures with default implementation.
All Dofstorages must be derived from this class but implementing only the
features of the above class.

The pwlinfunc.hh provides the implementation of linear base function with
polynom oeder 1 for triangles and a LagrangeMapper. Furthermore a
implementation of the corresponding function space.

For detailed description see the .hh files.
