[Building Sakai] how to entends Site object...

[John Bush]

any Entity is sakai has properties, basically you can attach meta data
of any sort.  Think of it as a custom field if you like.  So you
probably don't need that extra table

//to add
site.getProperties().addProperty("sponser, sponser)

//to access
site.getProperties().get("sponsor")

these show up in the sakai_site_property table in the database
