Applying patch of Jaime's modifications for SH ODF visualization on top of master
Apply new naming scheme to SH view toolbox
Glyph resolution minimum value set to 4 instead of6
corrections in CMakelist after merge  in medInria
some corrections after rebase
ShImage -> SHImage + various changes.
Corrected leaks + many changes.
More renaming sh->SH, some bug corrections.
More renaming sh->SH, some bug corrections.
Merge + minor changes (constness).
Resolve conflict.
Remove unused stuff.
Reove warning.
More factorisation.
Fixing ODF computation: legendre computation was wrong, using much less vertices for defining the mesh output of the spherical harmonic glyph filter (in vtkInria/vtkVisuManagement), removed useless normal computation. Caveat: the spherical harmonic toolbox form the diffusion workspace has to be set up correctly with initial computation values.
Updating user interface to meet new computation parameters in sh stuff.
