   *   "Numerical calculation of the rate of crystal nucleation in a

   *    Pieter Rein ten Wolde, Maria J. Ruiz-Montero, and Daan Frenkel,
   *    J. Chem. Phys. 104, pp. 9932-9947 (1996).
   *
   * Note that this version uses a single cutoff radius to decide 
   * membership in the list of neighbors, and does not have use a
   * distance-dependent weighting as used in the second reference above.
   *
   * The selection script can be utilized to look at specific types of
   * central atoms.  A dynamic selector can also be utilized.  By default, 
   * this class computes the Q_{l} and \hat{W}_{l} parameters up to l = 12.
   * The completed configurational averages of these values as
   * well as the distributions of atomic q_{l} and \hat{w}_{l} values
   * are then placed in .boq and .bow files.
