//     Defuzzification  of center of gravity
//
//     There can be many methods for defuzzification in a
//     fuzzy logic system. In Fuzz-C there are three macros
//     that must be defined for each Defuzzification method
//     supported.
//
//     fv_DeFuzzMethod(@CONSNAME)   Scratch variables that are needed.
//
//     fi_DeFuzzMethod(@CONSNAME)   Variable initialization. Called
//                                  from fuzzy function.
//
//     fm_DeFuzzMethod              Code to be executed each time a
//                                  consequence function is called
//
//     fd_DeFuzzMethod              Defuzz to Crisp routine called once
//                                  after all of the rules have been
//                                  executed.
//
//
//     For each consequence function the Fuzz-C preprocessor
//     can generate a crisp number for a specific degree of
//     membership and value for the area below the degree of
//     membership.
//
//     @CONSPOINT   // Single point crisp result
//     @CONSVOL     // Volume under the degree of membership
//
//
