// Deze functie staat los van het hele IE naar FF gedoe enzo, maar met deze functie kun je hashes (of assiciatieve arrays)

// Dan kun je doen newHash['one'] en dat is dan 1.

//   This script gives Netscape 6 the following IE methods:

//   removeNode(),replaceNode(),swapNode(),applyElement(),contains(),

//   insertAdjacentText(),insertAdjacentHTML(),insertAdjacentElement()


// Dit script geeft FF enzo wat extra functies die IE ook heeft, wel handig.
