// SHOW BY CLICK

// This self-invoking function returns init function. If you dynamicly modify or add new DOM structure, you can easyly run plugin for new elements.
// Init function needs one argument. Argument can be a DOM node or jQuery object containing element(s) for init.
// Basicly you can change selector by changing "selector" variable. Also you can give your dynamicly created trigger elements a className by changing "triggerClass" variable.
// In the "triggerText" array you can find text for trigger nodes or set it by adding custom "data-show-text" and "data-hide-text" attributes
// Please send BUG reports or any proposals to alexey.intertech@gmail.com
