| 2002-02-10 | Changed _update method to only update the text nodes instead   |
|            | rewriting the entire table. Also added support for mouse wheel |
|            | in IE6.                                                        |
| 2002-01-14 | Cleaned up for 1.0 public version                              |
| 2002-01-15 | Replace all innerHTML calls with DOM1 methods                  |
| 2002-01-18 | Minor IE6 bug that occured when dragging the mouse             |
| 2002-01-19 | Added a popup that is shown when the user clicks on the month. |
|            | This allows navigation to 6 adjacent months.                   |
| 2002-04-10 | Fixed a bug that occured in the popup when a date was selected |
|            | that caused surroundung months to "overflow"                   |
|            | This had the effect that one could get two October months      |
|            | listed.                                                        |
| 2002-09-06 | I had missed one place were window was used instead of         |
|            | doc.parentWindow                                               |
| 2003-08-28 | Added support for ensurin no date overflow when changing       |
|            | months.                                                        |
