      Scans the given string for a class type signature starting at the given index and returns the index of the last character. 
       ClassTypeSignature:
     { L | Q } Identifier
           { { / | . Identifier [ < TypeArgumentSignature* > ] }
           ;
      Note that although all "/"-identifiers most come before "."-identifiers, there is no syntactic ambiguity. This method will accept them without complaint.
      Parameters:
      string - the signature string
      start - the 0-based character index of the first character
      Returns:
      the 0-based character index of the last character

       TypeArgumentSignatures:
     < TypeArgumentSignature* >
      Note that although there is supposed to be at least one type argument, there is no syntactic ambiguity if there are none. This method will accept zero type argument signatures without complaint.
      Parameters:
      string - the signature string
      start - the 0-based character index of the first character
      Returns:
