everything has been embedded in this namespace. It took me some while to do that
I would appreciate if people do that automatically for new code/files

I tried also to cleanup a bit:

- using namespace std; : I tried to get rid of it but I stopped after lifecore
                         too much work to do for now
- minor fixes here and there
- removed norm.{h,c}pp and replaced by lifealg/vectorNorms.hpp
- minor fixes in the testsuite

* bump the version to 0.1.0pre2
* fix some configure problem with aztec
* cleanup in various places
* math.h -> cmath
* compilation fixes in testsuite
* use data/mesh to get the meshses in testsuite and not Meshes anymore

testsuite/data contains some general data like meshes
testsuite/official contains the official for LifeV that should work at all times
testsuite/development contains development tests for the latest features

doc/manual is the LifeV developer manual
doc/notes contains some notes on LifeV
doc/tex some TeX style files by me(CP)
