/**
 * A javascript module to handle calendar drag and drop in the calendar
 * month view navigation.
 *
 * This code is run each time the calendar month view is re-rendered. We
 * only register the event handlers once per page load so that the in place
 * DOM updates that happen on month change don't continue to register handlers.
