\ccDefinition
  
The class \ccRefName\ stores the description of a ridge line. The list
of halfedges defines a connected sequence of edges (but not as
oriented halfedges). The scalar $b$ paired with a halfedge $pq$ is the
barycentric coordinate of the crossing point $r$ with the ridge  : 
$r = b\times p + (1-b)\times q$.
