Class for geometric mapping of discontinuous finite elements (includes the mapping of faces onto element).

Current finite element, boundary element, internal face, boundary face for discontinuous finite elements.

  (aka buggy)
* source reformated and adapted to coding standard

not yet finished though.
it relies on boost but it is not mandatory

the next version of LifeV will have boost as mandatory

 * indent only with spaces(no tabs) : 4 spaces
 * ansi C/C++ format
 * break bracket from preblock (ie { on newline)
 * spaces around operators and parenthesis

now the code should way easier to read !
it could be that some places got uglier but overall it should
be much better

updated NEWS with work from Simone and Gilles (only the solvers in lifealg ;) )

added Alexandra and Gilles in the AUTHORS file

ignore automatically generated files

* more C++ standard compliance. unfortunately there are still lots
 of construct that are non standard (e.g. int v[size] where size is variable)
* fixed a lot of template specialization
* removed all ; after } (except for classes of course)
* tons of work remains to be done before LifeV can be fully compiled
  with g++-3.4. most lifesolver won't compile for example

* again lots of code that is obviously not compiled, this was broken
* fixed some interface that says they do somthing but in fact they don't
  for example returning something while they return nothing in fact

reverting evalResidual input varaibles so that input variables are first and modified variables are last in the calling sequence
