// note 1: This function deviates from PHP in returning a copy of the array instead
// note 1: of acting by reference and returning true; this was necessary because
// note 1: IE does not allow deleting and re-adding of properties without caching
// note 1: of property position; you can set the ini of "locutus.sortByReference" to true to
// note 1: get the PHP behavior, but use this only if you are in an environment
// note 1: such as Firefox extensions where for-in iteration order is fixed and true
// note 1: property deletion is supported. Note that we intend to implement the PHP
// note 1: behavior by default if IE ever does allow it; only gives shallow copy since
// note 1: is by reference in PHP anyways
// note 1: We cannot use numbers as keys and have them be reordered since they
// note 1: adhere to numerical order in some implementations
// example 1: var $array1 = {a:'IMG0.png', b:'img12.png', c:'img10.png', d:'img2.png', e:'img1.png', f:'IMG3.png'}
// example 1: natcasesort($array1)
// example 1: var $result = $array1
// returns 1: {a: 'IMG0.png', e: 'img1.png', d: 'img2.png', f: 'IMG3.png', c: 'img10.png', b: 'img12.png'}
