// fermion type is not F_CLASS_WILSON or F_CLASS_CLOVER or 
// F_CLASS_DWF the constructors exit with a general error.

// AlgWspect is derived from Alg and is relevant to  
// spectroscopy with Wilson type fermions (i.e. Wilson, Clover, Dwf). 
// The type of fermion is determined by the argument to the 
// constructor. If the fermion type is not F_CLASS_WILSON or 
// F_CLASS_CLOVER or F_CLASS_DWF the constructors exit with a 
// general error.
// Xiaodong: Only normal mesons are calculated
//           To calculate normal+extended mesons, use AlgWspectExtMeson
