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
update issue #160

@dolleg @asamake implement dof_marker using bimap
remove warnings
added interface for extracting values depending on the marker

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
