//         // Replace "myForm", and "DisplayedField" WITH THE NAME OF YOUR FORM AND INPUT FIELD RESPECTIVELY

//
//
//
// Required Files:
//
//         calendar.js   - contains all JavaScript functions to make the calendar work
//
//         calendar.html - frameset document (not required if you call the showCalendar()
//                         function.  However, calling showCalendar() directly causes
//                         the Java Virtual Machine (JVM) to start which slows down the
//                         loading of the calendar.)
//
//
// Files Generally Included:
//
//         calendar.gif  - image that looks like a little calendar
//
//         yourPage.html - page that contains a form and a date field which implements
//                         the calendar component
//
