/**
 * Flat mode version of the DatePicker. This means using the datepicker inline
 * on a page instead of having it popping up.
 * <p>
 * For using this you have to specify {@link ISelectCallback}, which will
 * handle the user selecting something in the date picker. There are two default
 * implementations of this callback: {@link AjaxSelectCallback} and
 * SelectCallback.
