// w_spect.h:

//
// classes defined in this header file
//   
//   WspectGinfo     --  implemented in w_ginfo.C
//
//     A support class to provide some global information to the rest
//     of this package. It is designed that all the rest classes be
//     derived from this class without any memory or executation
//     overhead.
//
//   WspectHyperRectangle
//                   --  implemented in w_hyper_rect.C
//
//   WspectMomenta   --  implemented in w_momenta.C 
//
//   WspectQuark     --  implemented in w_quark.C
//
//   WspectMesons    --  implemented in w_meson.C
//
//   WspectBaryon    --  implemented in w_baryon.C
//
//
//   added by Thomas and Xiaodong for extended mesons
//   WspectExtendedMesons  -- implemented in w_ext_mesons.C
//   WspectExtendedMesonsBE
//
//   WspectFuzzing
//
// Iff interested in the implementation details [calculation procedures,
// private member functions and quark propagator storage order]:
//          go to the end of this file for more comments.
