     * is used to bind module to the YUI instance.
     * @param version {string} version string.
     * @param details {object} optional config data:
     * requires: features that must be present before this module can be
     * attached.
     * optional: optional features that should be present if loadOptional
     * is defined.  Note: modules are not often loaded this way in YUI 3,
     * but this field is still useful to inform the user that certain
     * features in the component will require additional dependencies.

     * be attached automatically when this module is attached.  This
     * supports the YUI 3 rollup system -- a module with submodules

string `[object Object]` when used as a cache key.
