程序介绍：
This class can be used to display month calendars in HTML tables.
It takes a given month and year and generates an HTML table with the days of that month. The calendar start week day may be set to Sunday or Monday.
Special event days may exhibit the title of the event in the respective calendar table cell.
The class also shows links to pages that display the next and previous months.
The calendar presentation details can be configured with CSS styles.
The class generates XHTML compliant HTML.
