Add mutators

* Add get/set methods to modify or retrieve GMSH geo parameters
  directly in the application source code.
Rename geo getters to feelpp standard
Merge branch 'develop' of github.com:feelpp/feelpp into feature/geomod
@Trophime It seems that the problem is fixed regarding the Eigen assertion in
case of fixed size matrices. Now I differentiate the case when the number of
columns is 1 and > 1.

update issue #158
@StephaneVeys test_lambda works now ok. There are still some features of the
language which do not support the Lambda framework and you still need to pass
the function operators (id, grad, ...) and not the function itself.
Hopefully I will be able to fix that soon
bump up to feel++ 0.95.0
update ChangeLog
0.94.0 will not be released publicly due to a technical issue while doing a prerelease
fix sequential case: in sequential subksp were overriding the ksp
try to have better log info
@vincentchabannes @asamake Now use the Dof data structure to store the global dof
information and not a tuple (Dof derives from a tuple for backward
compatibility)
define also LocalDof and LocalDofSet for the new dof_Table data structure
which allows to go back and forth between the local and global dof using boost::bimap

added options for gmsh.domain
now everything is customizable from section gmsh.domain
loadMesh() by default loads a hypercube domain and passes now all options from
loadMesh() and associated options
added rebuild option to gmsh section
added rebuild option to gmsh section
added laplacian with dirac on the right hand side
@feelpp/feelpp @feelpp/dot here is an simple example  in 2D of a laplacian
with a dirac on the right habd side
added center of the ellipsoid to the mesh
add _h and use _h
