//  first review        : january 31-2004 - code review and new method "Array.getNormalized" that will return a normalized copy of the still unchanged remaining operand array;
//  first public release:    july 05-2003 - normalizes array entries, that is every entered object thats type and values already exist as properties of an object before within the processed array gets deleted or in other words, after normalizing no redundant informations can be found within the processed array;

  //return arr;                     // bis hier verhaelt sich die methode wie "getNormalized" aber nicht wie "normalize"; // till here the method rather is a "getNormalized" than a real "normalize" one;
