/*funkcja referenceToElement.addEventListener('nameOfEvent',referenceToFunction,phase)
gdzie (DOM2)'nameOfEvent' zapisuje się np:'mouseover' 'click' 'keyup' itd. RefrenceToFunction może być a direct function reference.
Phase=false oznacza bubbling (nie wiem czy tak jest w DOM2, w IE jeśli np. link był w div i miał eventhandler,event widział link i div, link najpierw)
Phase=true oznacza capturing, (Mozilla) orginalnie div widział event,link nie (chyba że kod nakazywał kontynuację)
W DOM2 capture powoduje,że event widzi tylko div (czyli event jest spożytkowany przez ancestors of target element) */
/* Z Wikipedii:http://en.wikipedia.org/wiki/Whitespace_(computer_science):Still, for most programming languages, abundant use of whitespace, especially trailing whitespace at the end of lines, is considered a nuisance. In interpreted languages, parsing of unnecessary whitespace may affect the speed of execution. In markup languages like HTML, unnecessary whitespace increases the file size, and may so affect the speed of transfer over a network. On the other hand, unnecessary whitespace can also inconspicuously mark code, similar to, but less obvious than comments in code. This can be desirable to prove an infringement of license or copyright that was committed by copying and pasting.*/
