// Header file for all alg classes relevant to Wilson-type fermion
// three point functions. The type of glue or fermion is given as
// an argument of type Lattice& 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.
