adding tools to robustly compute the orientation of three given points
benchmark completed
cleaning + example + documentation page
 cleaning doc and concepts
an adapter to orientation functor in order to have a customizable predicate
2d to 2D
renamming 2D into 2, the number gives the number of points required minus one
 radius functor added for alpha-shapes
 renamming (orientation = general, halfPlane in the linear case), general concept of orientation functor and documentation updated
merging with master
edits in doxygen comments
