/* Tiki-Wiki Countdown plugin
 *
 * This is an example plugin to indicate a countdown to a date.
 * Plugins are called using the syntax
 * {COUNTDOWN(end=>string date)} to reach all targets!{COUNTDOWN}
 * Name must be in uppercase!
 * params is in the form: name=>value,name2=>value2 (don't use quotes!)
 * If the plugin doesn't use params use {NAME()}content{NAME}
 *
 * The function will receive the plugin content in $data and the params
 * in the asociative array $params (using extract to pull the arguments
 * as in the example is a good practice)
 * The function returns some text that will replace the content in the
 * wiki page.
