docs: NAME:
  
             Freqs
  
          PURPOSE:
  
             return the frequencies corresponding to a torus
  
          INPUT:
  
             jr - radial action (scalar)
  
             jphi - azimuthal action (scalar)
  
             jz - vertical action (scalar)
  
             tol= (object-wide value) goal for |dJ|/|J| along the torus
  
          OUTPUT:
  
             (OmegaR,Omegaphi,Omegaz)
