/**
 * Convert a string to a date using the {@link SimpleDateFormat} class. If you want to convert from a Date to a String,
 * use the {@link FmtDate} processor.
 * <p>
 * examples of arguments to the cellprocessor are:
 * <p>
 * <code>"MM/dd/yy"</code> to parse dase such as "01/29/02" <br>
 * <code>"dd-MMM-yy"</code> to parse dates such as "29-Jan-02" <br>
 * <code>"yyyy.MM.dd.HH.mm.ss"</code> To parse dates such as "2002.01.29.08.36.33"<br>
 * Or even <code>"E, dd MMM yyyy HH:mm:ss Z"</code> To parse "Tue, 29 Jan 2002 22:14:02 -0500"
