/**

 * Create a new calendar by enabling or cloning the default calendar,
 * changing the date argument to use the correct date field(s), and setting
 * up the year, month, day, week, and block views with the desired styles 
 * and fields.
 * 
 * Unlike previous versions of the Calendar module, there is just a single
 * Date argument instead of year, month, and day arguments. The argument
 * value will be YYYY-MM-DD for a day, YYYY-MM for a month, YYYY for a
 * year, and YYYY-W99 for a week. There is a default option to set the 
 * argument to the current date when the argument is empty.
 * 
 * A calendar display creates calendar navigation and links to 
 * multiple displays for the year, month, day, or week views. The actual
 * displays are created by attaching calendar views that use whatever
 * styles are desired for those pages. 
 * 
 * Calendar views are attachments to create the year, month, day,
 * and week displays. They can be set to use any style, either a
 * calendar style or any other Views style, like teasers or lists.
 * If you don't want to use one of them, don't attach it to
 * anything. Only the attached views will show up in the calendar.
 * 
 * A calendar block will create a calendar block for the
 * view results. Attach a block view to the block and set up the
 * desired style in the block view.
