Some updates in the datas
Added the two new global variables in the main files.
Compatibility update
Fixing a small issue due to the new position of BCInterface
adding a preliminar version of the 3D FSI in the multiscale framework.

The same model is used both for both partitioned and monolithic solvers. The
changes are in the data file specified in MultiscaleData/Models/MultiScale_3DFSIserial1.dat
adding the 3D FSI model to the multiscale framework
removing white spaces
adding the data files for monolithic and segregated solvers in the multiscale
* Changing the name of some methods, to avoid ambiguity.
* Integration of BCInterface in the 1D model.

NOTE: If you don't whant to read BC from a file, because you prefer to set them manually, you can do it (see test_onedmodel for an example).
Test updated.
Swithing to P1P1 for the models
Updating simulation files
Wrong simulation time corrected.
Enabling the coupling interface for FSI. From the coupling point of view the work is finished, however still some changes have to be done in Model_FSI3D.

NOTE: Paolo, after few fixes it compiles. We can continue the discussion Monday about the other modifications.
Data files for the coupling updated
Adding some files for stationary Navier-Stokes simulation.
Stationary Navier-Stokes enabled.
Fixing a small issue
Added three new boundary condition.
