* 
* Details
* -------
*  
* "KALENDER", which is basically Dutch for "Calendar",
* is a simple calendar tool that can be embedded into a website using
* the MODx content management system.
* 
* 
* Installing
* ----------
* 
* 1. Download the snippet zip file from the MODx Repository.
* 
* 2. Extract the snippet zip file and place it as a folder called "kalender" in
*    your "/assets/snippets/" folder on your server.
* 
* 3. You will find the following files and folders extracted:
* 
*    => readme.txt
*    => kalender_screenshots.gif   
*    => kalender_snippet.php
*    => themes
*       => gold
*          => images
*             => (images - *.gif files)
*          => theme.css
*          => theme.php
*    => js
*       => (overLib Javascript library - *.js files)  
*       
* 4. Create a new snippet called "Kalender" at the MODx Manager
*    (Resources=>Manager Resources=>Snippets=>New snippet)
*    
* 5. Copy and paste everything from the file "kalender_snippet_copy_this.php"
*    as Snippet code and "Save".
* 
* 
* Embedding Kalender into your template
* -------------------------------------
* 
* To display the calendar to your website template, just use this snippet call:
*  
* [!Kalender?&parent=`1257`!]
*  
* Where &parent=`1257` points to the document id number where Kalender data resides.
* 
* MODx content documents that are stored as 'children' of $parent will feed Kalender.
* 
* 
* Managing Kalender data using the MODx manager
* ---------------------------------------------
*  
* 1) Only documents that are not a folder (isfolder=0) that is placed either directly
*    as a 'child-document' or any level below $parent will be reflected in the
*    Kalender.
*     
* 2) Use 'pub_date' to mark your event in the Kalender.
*  
* 3) You may also use 'unpub_date' for events that will last more than 1 day long.
*  
* 4) Use "00:00:00" (midnight) to leave time notations blank.
*  
* 5) When modifying the theme, take note that all CSS classes located in "theme.css"
*    as well as PHP variables located in "theme.php" MUST remain in-tact.
*     
* * New themes may be created by simply copying all elements in the default 'gold'
*   theme folder and pasting it as a new folder with a new theme name of your
*   choice.
*   
* More on Themes
* --------------
* 
* 
* By default, we have the 'gold' theme available for you.
* 
* But if you wish to create your own theme, just create a new folder in the "themes" 
* directory and copy EVERYTHING from the default 'gold' folder.
* 
* You are free to change the values, dimensions, etc of the theme files.
* But it is IMPORTANT that you retain all file names, css classes and php 
* variables intact.  
* 
* Example:
* 
*   If I wanted to create an "aqua" theme my file structure would look like:
*   
*   => themes
*       => gold
*          => images
*             => (images - *.gif files)
*          => theme.css
*          => theme.php
*       => aqua
*          => images
*             => (images - *.gif files)
*          => theme.css
*          => theme.php         
*          
*   And my snippet call would look like this:
*   
*   [!Kalender?&parent=`1257` &theme=`aqua`!]
* 
* 
* Snippet Parameters Explained
* ----------------------------
*  
* $theme [string] ['gold'] : Color theme (should be same name as theme folder).
*  
* $parent [int] [-1] : MODx document/folder id where calendar documents are stored.
*  
* $mm [int] [current month] : Month without leading zeros. Defaults to current month
*                             when blank.
*  
* $yyyy [int] [current year] : Year. Defaults to current year when blank.  
* 
* 
* Added parameters:
* -----------------
*
* $timezone [string]
*   Set timezone as described on http://us2.php.net/manual/en/function.date-default-timezone-set.php
*     this parameter is added to prevent php5 error messages
*   You could also past this into the settings tab at default settings:
*     &timezone=Timezone link text;string;America/Los_Angeles
*
* $lang [string] [ 'en' | 'de' | 'fr' | 'nl' (etc.) ]
*   language to use for the calendar
*
* $dateFormat [string] [ 'mdy' | 'dmy' ]
*   `mdy` will display in English format i.e. March 21, 2007 (default)
*   `dmy` will display in other format i.e. 21 March 2007
*
* $dayLen [int] [ 1 | 2 | 3 ]
*   Number of characters from the daynames to show (max. 3)
*
* $showInfo [string] [ 'intro' | 'content' | 'both' ]
*   `intro` will show summary (introtext) only
*   `content` will show  content only
*   `both` will show both introtext and content (default)
*
* $links [int] [ 0 | 1 ]
*   0 just highlights dates with events
*   1 will make dates with events linkable
*
* Credits
* ------- 
*  
* As with all calendar apps, this one isn't the most original so credit goes to 
* where credit is due.
* 
* 1) The idea for this snippet came out of EasyPHPCalendar.
*    (http://www.easyphpcalendar.com)
*    
* 2) Also, Kalender extensively uses Erik Bosrup's "overLib" Javascript library
*   (http://www.bosrup.com/web/overlib) 
* 
* License
* -------
* 
* Everything's FREE. No restrictions. Seriously.
* 
* Just remember, you're using this at your own risk.
* 
* But if you want to modify, expand and change the code, feel absolutely free to do so.
* 
* Just keep in mind to respect Erik Bosrup's license when using his overLib Javascript
* library.
