Computes the list of stable comes from a particle list.
This class does the first fundamental task of te cone algorithm: it is used to compute the list of stable cones given a list of particles.

int siscone_spherical::CSphstable_cones::get_stable_cones | ( | double | _radius | ) |
compute stable cones.
This function really does the job i.e. computes the list of stable cones (in a seedless way)
_radius | radius of the cones |
