// original by: Carlos R. L. Rodrigues (http://www.jsfromhell.com)
// improved by: Brett Zamir (http://brett-zamir.me)
// note 1: Important note: Per the ECMAScript specification,
// note 1: objects may not always iterate in a predictable order
// example 1: array_chunk(['Kevin', 'van', 'Zonneveld'], 2)
// returns 1: [['Kevin', 'van'], ['Zonneveld']]
// example 2: array_chunk(['Kevin', 'van', 'Zonneveld'], 2, true)
// returns 2: [{0:'Kevin', 1:'van'}, {2: 'Zonneveld'}]
// example 3: array_chunk({1:'Kevin', 2:'van', 3:'Zonneveld'}, 2)
// returns 3: [['Kevin', 'van'], ['Zonneveld']]
// example 4: array_chunk({1:'Kevin', 2:'van', 3:'Zonneveld'}, 2, true)
// returns 4: [{1: 'Kevin', 2: 'van'}, {3: 'Zonneveld'}]
