    + added "[]" operator overloading for the HBCharacter type class:
      <string>[n] : access
      assign is not implemented ( <string>[n] := <char> )
      negative index is not implemented ( <string>[-n] )

    + added "$" operator overloading for the following type classes:
      HBCharacter : <char> $ <array|hash>
      HBDate      : <date> $ <array|hash>
      HBLogical   : <logical> $ <array|hash>
      HBNil       : <nil> $ <array|hash>
      HBNumeric   : <numeric> $ <array|hash>

    ; all the new extended types, has a ::ClassName with the "HB" prefix.
