/**
* The CollationElementIterator class is used as an iterator to walk through 
* each character of an international string. Use the iterator to return the
* ordering priority of the positioned character. The ordering priority of a 
* character, which we refer to as a key, defines how a character is collated in 
* the given collation object.
* For example, consider the following in Slovak and in traditional Spanish collation:
* <pre>
* "ca" -> the first key is key('c') and second key is key('a').
* "cha" -> the first key is key('ch') and second key is key('a').</pre>
* And in German phonebook collation,
* <pre> \htmlonly "&#x00E6;b"-> the first key is key('a'), the second key is key('e'), and
* the third key is key('b'). \endhtmlonly </pre>
* The key of a character, is an integer composed of primary order(short),
* secondary order(char), and tertiary order(char). Java strictly defines the 
* size and signedness of its primitive data types. Therefore, the static
* functions primaryOrder(), secondaryOrder(), and tertiaryOrder() return 
* int32_t to ensure the correctness of the key value.
* Example of the iterator usage: (without error checking)
* <pre>
* \code
* void CollationElementIterator_Example()
* {
* UnicodeString str = "This is a test";
* UErrorCode success = U_ZERO_ERROR;
* RuleBasedCollator* rbc =
* (RuleBasedCollator*) RuleBasedCollator::createInstance(success);
* CollationElementIterator* c =
* rbc->createCollationElementIterator( str );
* int32_t order = c->next(success);
* c->reset();
* order = c->previous(success);
* delete c;
* delete rbc;
* }
* \endcode
* </pre>
* 
* The method next() returns the collation order of the next character based on
* the comparison level of the collator. The method previous() returns the
* collation order of the previous character based on the comparison level of
* the collator. The Collation Element Iterator moves only in one direction
* between calls to reset(), setOffset(), or setText(). That is, next() 
* and previous() can not be inter-used. Whenever previous() is to be called after 
* next() or vice versa, reset(), setOffset() or setText() has to be called first
* to reset the status, shifting pointers to either the end or the start of
* the string (reset() or setText()), or the specified position (setOffset()).
* Hence at the next call of next() or previous(), the first or last collation order,
* or collation order at the spefcifieid position will be returned. If a change of
* direction is done without one of these calls, the result is undefined.
* 
* The result of a forward iterate (next()) and reversed result of the backward
* iterate (previous()) on the same string are equivalent, if collation orders
* with the value 0 are ignored.
* Character based on the comparison level of the collator. A collation order 
* consists of primary order, secondary order and tertiary order. The data 
* type of the collation order is int32_t. 
*
* Note, CollationElementIterator should not be subclassed.
