// Description: Gets URL parameters, decodes them and puts them into the two arrays "key"
// and "value". Also lets a script access a certain parameter (key) directly.
// Usage:
// get_value ( Gets the value for the given parameter.
// parameter The URL parameters whose value is required.
// )
// Returns:
// value The value of the URL parameter.
//
// get_parameters ( Gets all the URL parameters and saves them in the arrays "key" and "value". This is done automatically, so don't use this function!
// )
// HTML usage:
// For a URL http://www.whatever.com/whatever.html?bla=1&etc=2&whatever=3
//
//
//
//
//
// will show two alert boxes with "bla = 1" and "3".

value = new Array();
