Converts the array-like object into a true array.
E.g. a DOM nodeList:
var nodeList = document.getElementsByTagName('a'),
array = Pablo.toArray(nodeList);
alert(array.length);
E.g. function arguments:
function something(a, b, c, d){
var args = Pablo.toArray(arguments);
alert(args.indexOf('tree'));
}
something('cat', 'dog', 'tree', 'flower');
