* Thanks to Maik Lindner (http://nifox.com) for his help developing this class
* Support, feature requests and bug reports please at : gt AT corissia DOT com

* -------- You may remove all comments below to reduce file size -------- *

* This class generates calendars as a html table (XHTML Valid)
* Supported views: month and year view
* Supported dates:
* 1. Using PHP native date functions (default): 1902-2037 (UNIX) or 1971-2037 (Windows)
* 2. Using ADOdb Date Library : 100-3000 and later [limited by the computation time of adodb_mktime()].
* You can find the ADOdb Date Library at http://phplens.com/phpeverywhere/adodb_date_library
* To use the ADOdb Date Library just include it in your main script. The Active Calendar class will use the library functions automatically.
* Supported features:
* 1. Static calendar without any links
* 2. Calendar with month's or year's view navigation controls
* 3. Calendar with linkable days (url or javascript)
* 4. Calendar with a date picker (year ot month mode)
* 5. Calendar with event days (css configutation) and event links
* 6. Calendar with optionally linkable event contents
* The layout of can be configured using css, as the class generates various html classes
* Please read the readme.html first and check the examples included in this package
