Implements	`osid.OsidList`
Description	Like all `OsidLists`, `ItemPeerList` provides a means for accessing `ItemPeer` elements sequentially either one at a time or many at a time. Examples: while (ipl.hasNext()) { ItemPeer peer = ipl.getNextItemPeer(); } or while (ipl.hasNext()) { ItemPeer[] peers = ipl.getNextItemPeers(ipl.available()); }
Method	getNextItemPeer
