[kronolith] Alternate views

[Elliot Anders]

Thanks!
This looks very useful.  I actually figured out what I needed, and  
replied only to myself, but this looks even better.  Here's what I  
discovered.

It is extremely easy to make a new view.

1. Copy all associated files, rename them, and replace appropriate  
instances of the view name with your view name.  I based mine on the  
year view, so
/kronolith/year.php
/kronolith/lib/Views/Year.php
/kronolith/templates/year
2. In /kronolith/lib/Kronolith.php find all instances of WorkWeek,  
workweek, workweek.php  (works better than year in this file because  
year has alternate meanings) and copy them replacing the above three  
items with the appropriate replacements.
3. Adjust /kronolith/lib/Views/YourViewName.php to show your new view.

Thanks Chuck and Jan for making this so easy.

My new question is: is there an easy way to embed kronolith in a non  
horde website?  I feel like I've seen an article on the wiki on using  
instantiating horde outside of horde but I can't seem to find it right  
now. Basically I wan to pull this calendar I just made off our webmail  
installation and into our main website, and have it show up within our  
framework.  Are there instructions for screen-scaping horde somewhere?

Thanks again,
Elliot
