minor typo
first draft for idf() doc
Merge branch 'develop' of https://github.com/feelpp/feelpp into develop
update integrator on for a list of marker
various minor changes
  - add addRegions() to exporter to get partitioning
  - Magnetostatic is in electromag
  - test_project in sequential
Issue #326:
- MeshPoints: Added constructor with worlcomm
- Implemented option to export data per processor with sequential
  worldcomm
- cleanup
Merge branch 'develop' of https://github.com/feelpp/feelpp into develop
added polynomial order for expressions
-verbose in parallel case
Merge branch 'develop' of https://github.com/feelpp/feelpp into develop
fixes 399:
 - enable Fast Marching for hypercube: it works flawlessly
 - add hypercube support for application dist2walls
 - add an option to compute the distance function only from a markedsurface
    use --marker="name of the marker" to enable that. Otherwise it uses
    the entire boundary
up #399
 - add cfg files
Fix issue #398
fix createSubmesh<ELEMENTS> when a specific MeshTag is given for the output mesh
add a part to FAQ (doc)
Merge branch 'develop' of https://github.com/feelpp/feelpp into develop
Issue #326:
- Removed old code used for renumbering the markers
- Disable ensight gold exporter if we don't have MPI IO
Merge branch 'develop' of https://github.com/feelpp/feelpp into develop
Issue #326:
- Does not crash anymore when MPI IO is not detected (A warning is
  displayed)
- Use a macro to disable MPI IO code (not the option as previously done)
up relation mesh support in integrator (range can be also a submesh of test/trial mesh)
add ExtendedDofTable info
