/**
* 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>
* <LI>mmm - month (in words)</LI>
* <li>yyyy - year</LI>
* </UL>
* </LI>
* </UL>
