/**
 * \file
 * \brief C API: ICU Plugin API 
 *
 * <h2>C API: ICU Plugin API</h2>
 *
 * <p>C API allowing run-time loadable modules that extend or modify ICU functionality.</p>
 *
 * <h3>Loading and Configuration</h3>
 *
 * <p>At ICU startup time, the environment variable "ICU_PLUGINS" will be 
 * queried for a directory name.  If it is not set, the preprocessor symbol 
 * "DEFAULT_ICU_PLUGINS" will be checked for a default value.</p>
 *
 * <p>Within the above-named directory, the file  "icuplugins##.txt" will be 
 * opened, if present, where ## is the major+minor number of the currently 
 * running ICU (such as, 44 for ICU 4.4, thus icuplugins44.txt)</p>
 *
 * <p>The configuration file has this format:</p>
 *
 * <ul>
 * <li>Hash (#) begins a comment line</li>
 * 
 * <li>Non-comment lines have two or three components:
 * LIBRARYNAME     ENTRYPOINT     [ CONFIGURATION .. ]</li>
 *
 * <li>Tabs or spaces separate the three items.</li>
 *
 * <li>LIBRARYNAME is the name of a shared library, either a short name if 
 * it is on the loader path,  or a full pathname.</li>
 *
 * <li>ENTRYPOINT is the short (undecorated) symbol name of the plugin's 
 * entrypoint, as above.</li>
 *
 * <li>CONFIGURATION is the entire rest of the line . It's passed as-is to 
 * the plugin.</li>
 * </ul>
 *
 * <p>An example configuration file is, in its entirety:</p>
 *
 * \code
 * # this is icuplugins44.txt
 * testplug.dll    myPlugin        hello=world
 * \endcode
 * <p>Plugins are categorized as "high" or "low" level.  Low level are those 
 * which must be run BEFORE high level plugins, and before any operations 
 * which cause ICU to be 'initialized'.  If a plugin is low level but 
 * causes ICU to allocate memory or become initialized, that plugin is said 
 * to cause a 'level change'. </p>
 *
 * <p>At load time, ICU first queries all plugins to determine their level, 
 * then loads all 'low' plugins first, and then loads all 'high' plugins.  
 * Plugins are otherwise loaded in the order listed in the configuration file.</p>
 * 
 * <h3>Implementing a Plugin</h3>
 * \code
 * U_CAPI UPlugTokenReturn U_EXPORT2 
 * myPlugin (UPlugData *plug, UPlugReason reason, UErrorCode *status) {
 *   if(reason==UPLUG_REASON_QUERY) {
 *      uplug_setPlugName(plug, "Simple Plugin");
 *      uplug_setPlugLevel(plug, UPLUG_LEVEL_HIGH);
 *    } else if(reason==UPLUG_REASON_LOAD) {
 *       ... Set up some ICU things here.... 
 *    } else if(reason==UPLUG_REASON_UNLOAD) {
 *       ... unload, clean up ...
 *    }
 *   return UPLUG_TOKEN;
 *  }
 * \endcode
 *
 * <p>The UPlugData*  is an opaque pointer to the plugin-specific data, and is 
 * used in all other API calls.</p>
 *
 * <p>The API contract is:</p>
 * <ol><li>The plugin MUST always return UPLUG_TOKEN as a return value- to 
 * indicate that it is a valid plugin.</li>
 *
 * <li>When the 'reason' parameter is set to UPLUG_REASON_QUERY,  the 
 * plugin MUST call uplug_setPlugLevel() to indicate whether it is a high 
 * level or low level plugin.</li>
 *
 * <li>When the 'reason' parameter is UPLUG_REASON_QUERY, the plugin 
 * SHOULD call uplug_setPlugName to indicate a human readable plugin name.</li></ol>
