   *  Presentation method to show a date input field with a popup calendar. Calendar is accessed
by clicking the icon
   *  next to input field. For now, the only date format supported is mm/dd/yyyy. If value
<code>$today</code> is passed, the date in the input field will default to today's
date.
   *  <p>Options:
   *  <UL>
   *  <LI><code>$<name>.style.formName</code> - form name where the
control is displayed; default=DefaultCustomizer</LI>
   *  <LI><code>$<name>.style.format</code> - date format to use for
return value; default=mm/dd/yyyy.
   * The date format can have three types of separators: hyphen(-), space( ), or slash(/),
but must be consistent in their usage. E.g.
   * d/m/yyyy
   * The acceptable tokens are :
   *   <UL>
   *   <LI>d - day</LI>
   *   <LI>dd - day (padded with 0 if less than 10)</LI>
   *   <LI>m - month (in numbers)</LI>
   *   <LI>mm - month (in numbers, padded with 0 if less than 10)</LI>
