示例1: concat
/**
* Concatenates one or more foreach-able object into an Iterator.
* If no objects provided, returns an empty iterator.
* \AppendIterators provided will be deep copied.
* This means changes to \AppendIterator parameters will not be reflected
* in the resulting \Iterator.
* @return \Iterator
*/
