 *
 * Inversion of control for dom elements.
 * Allows you to bind custom logic, plugins, etc. to a dom element.
 * The binding is referencing passed data attributes.
 * If data-option-* has been set, options will available in callback.
 *
 * data-instance: instance name referencing instance name
 * data-option-*: custom options for instance
 * HTML:
 * <div data-instance="myInctance" data-attr-foo="bar"></div>
 *
 * JS:
 * <script type="text/javascript">
 *  jq.domIoC('myInstance', function (element, options) {
 *      element.text(options.foo);
 *      element.bazPlugin(options);
 *      bazPlugin(element,options);
 *  });
 * </script>
