/**
 * AgentCommitmentIterator provides access to these objects sequentially, one
 * at a time.  The purpose of all Iterators is to to offer a way for OSID
 * methods to return multiple values of a common type and not use an array.
 * Returning an array may not be appropriate if the number of values returned
 * is large or is fetched remotely.  Iterators do not allow access to values
 * by index, rather you must access values in sequence. Similarly, there is no
 * way to go backwards through the sequence unless you place the values in a
 * data structure, such as an array, that allows for access by index.
