  *
  * Format Date object in different ways.
  * <p>
  * The date tag will allow you to format a Date in a quick and easy way.
  * You can specify a <b>custom format</b> (eg. "dd/MM/yyyy hh:mm"), you can generate
  * <b>easy readable notations</b> (like "in 2 hours, 14 minutes"), or you can just fall back
  * on a <b>predefined format</b> with key 'struts.date.format' in your properties file.
  * </p>
  *
  * <p>
  * If that key is not defined, it will finally fall back to the default DateFormat.MEDIUM
  * formatting.
  * </p>
  *
  * <p>
  * <b>Note</b>: If the requested Date object isn't found on the stack, a blank will be returned.
  * </p>
  *
  * <p>
  * Configurable attributes are:
  * </p>
  *
  * <ul>
  *    <li>name</li>
  *    <li>nice</li>
  *    <li>format</li>
  * </ul>
  *
  * <p>
  * Following how the date component will work, depending on the value of nice attribute
  * (which by default is false) and the format attribute.
  * </p>
  *
  * <p>
  * <b><u>Condition 1: With nice attribute as true</u></b>
  * </p>
  * <table border="1" summary="">

	* The date tag will allow you to format a Date in a quick and easy way.
	* You can specify a <b>custom format</b> (eg. "dd/MM/yyyy hh:mm"), you can generate
	* <b>easy readable notations</b> (like "in 2 hours, 14 minutes"), or you can just fall back
	* on a <b>predefined format</b> with key 'struts.date.format' in your properties file.

	*
	* <p>
	* If that key is not defined, it will finally fall back to the default DateFormat.MEDIUM
	* formatting.
	* </p>
	*
	* <p>
	* <b>Note</b>: If the requested Date object isn't found on the stack, a blank will be returned.
