Detailed Description

Framework to perform normal point projection on a soup of topologic faces.

Internally, the utility class GeomAPI_ProjectPointOnSurf is heavily used.
The algorithmics are pretty slow : for a point to be projected, the projection of that point is performed on each loaded TopoDS_Face with the help of GeomAPI_ProjectPointOnSurf.
The minimal distance amongst all the projection candidates is computed to get the final projected point
