This function is required for the computation of the skein tree of a polygonal link. The tree is built by iterating the skein relation and geometrically constructing the L_0 and L_{sw} configuration (of a Conway skein triple).

points3D 
an N x 3 matrix of the x, y, z coordinates of a polygonal link 
ends 
a vector of positive integers defining the separators of the polygonal link 
M 
the intersection matrix of the polygonal link 
leaves 
a list containing the binary indices of the tree leaves 
tree 
a list containing the skein tree. Each slot contains the slots
