//Base code from E.Suez - esuez@mail.utexas.edu
//Base code available at http://uts.cc.utexas.edu/~esuez/cal5.html
//Modified by A.Pocock - anthony@wnc.com.au - http://www.wnc.com.au
//Mods include:
//- Change to ddmmyyyy format
//- removed dropdown list functionality
//- added support to return a ddmmyy value to a field
//- ability to open calendar to current value of the selected field
//- support for multiple date selectors on a page to return values to different fields
//- developed specifically to be compatible with Lotus Domino R5, but should work with other IDE´s
//
//To install Date Picker:
//- Copy code listed below to the JavaScript header
//- in the onClick() event of the button or graphic which is to spawn the calendar, include
// a function call to opencalendar("fieldname") passing the fieldname you want the date returned
// to as the parameter.
//- make calls to opencalendar("fieldname") for any subsequent fields which need a Date Picker.
//
//
//Comments and suggestions are welcome. Send to anthony@wnc.com.au
//A demo of this working under domino can be seen at http://www.wnc.com.au/products/datepick.nsf
