/**
 * Initialize ICU.
 *
 * Use of this function is optional. It is OK to simply use ICU
 * services and functions without first having initialized
 * ICU by calling u_init().
 *
 * u_init() will attempt to load some part of ICU's data, and is
 * useful as a test for configuration or installation problems that
 * leave the ICU data inaccessible. A successful invocation of u_init()
 * does not, however, guarantee that all ICU data is accessible.
 *
 * Multiple calls to u_init() cause no harm, aside from the small amount
 * of time required.
 *
 * In old versions of ICU, u_init() was required in multi-threaded applications
 * to ensure the thread safety of ICU. u_init() is no longer needed for this purpose.
 *
 * @param status An ICU UErrorCode parameter. It must not be <code>NULL</code>.
 * An Error will be returned if some required part of ICU data can not
 * be loaded or initialized.
 * The function returns immediately if the input error code indicates a
 * failure, as usual.
 *
 * @stable ICU 2.6

/**
 * Clean up the system resources, such as allocated memory or open files,
 * used in all ICU libraries. This will free/delete all memory owned by the
 * ICU libraries, and return them to their original load state. All open ICU
 * items (collators, resource bundles, converters, etc.) must be closed before
 * calling this function, otherwise ICU may not free its allocated memory
 * (e.g. close your converters and resource bundles before calling this
 * function). Generally, this function should be called once just before
 * an application exits. For applications that dynamically load and unload
 * the ICU libraries (relatively uncommon), u_cleanup() should be called
 * just before the library unload.
 * 
 * u_cleanup() also clears any ICU heap functions, mutex functions or
 * trace functions that may have been set for the process. 
 * This has the effect of restoring ICU to its initial condition, before
 * any of these override functions were installed. Refer to
 * u_setMemoryFunctions(), u_setMutexFunctions and 
 * utrace_setFunctions(). If ICU is to be reinitialized after
 * calling u_cleanup(), these runtime override functions will need to
 * be set up again if they are still required.
 * 
 * u_cleanup() is not thread safe. All other threads should stop using ICU
 * before calling this function.
 * 
 * Any open ICU items will be left in an undefined state by u_cleanup(),
 * and any subsequent attempt to use such an item will give unpredictable
 * results.
 * 
 * After calling u_cleanup(), an application may continue to use ICU by
 * calling u_init(). An application must invoke u_init() first from one single
 * thread before allowing other threads call u_init(). All threads existing
 * at the time of the first thread's call to u_init() must also call
 * u_init() themselves before continuing with other ICU operations. 
 * 
 * The use of u_cleanup() just before an application terminates is optional,
 * but it should be called only once for performance reasons. The primary
 * benefit is to eliminate reports of memory or resource leaks originating
 * in ICU code from the results generated by heap analysis tools.
 * 
 * Use this function with great care!
