/**
* Calendar navigator window
*
* This is a calendar applicaion that simply
* provides a visual way for users to choose
* a day to jump to on the scheduler app
* It prints out a XHTML 1.1 standard calendar
*
* The calendar should be opened using a javascript
* window.open() function. The recommended syntax would be:
* window.open('calendar_opening_file.php','calendar','width=###,height=###,scrollbars=no,location=no,menubar=no,toolbar=no,resizable=yes');
* subbing actual calendar opener filename and width/height size
* Note: void(0); is needed after the window.open() function if used in a link
* Ex) <a href="javascript: window.open('cal_test.php','calendar','width=280,height=280,scrollbars=no,location=no,menubar=no,toolbar=no'); void(0);">Link to open calendar</a>
*
* Extend the class and override any functions to add/change functionality
