[Dev] Clouds inspector tool

[Morgen Sagen]

Having spent some time defining clouds in our schema, I decided I  
needed a tool to help me visualize the cloud definitions (especially  
now that we have cloud/endpoint inheritance) and to easily see what  
items belong to a given item's various clouds.  I modified my  
repository servlet (available either via subversion at  
http://svn.morgen.com/projects/parcels/ or as a tarball  
http://svn.morgen.com/downloads/parcels/parcels-2004-08-03.tar.gz) to  
display more information about items.  If you are running those parcels  
you will be able to point your web browser at  
http://localhost:1888/repo?tool=clouds and get a list of all clouds  
defined in your repository.  Click on any kind and it will show you,  
among other details, all clouds/endpoints that pertain to that kind  
(and which clouds they were inherited from).  For any item it will also  
show all items that are members of that item's cloud(s).  Although it  
won't be running all the time, if you're lucky you might see a running  
instance of this at http://morgen.com:1888/repo/?tool=clouds

Again, to run these parcels yourself, download them, set your PARCELDIR  
environment variable to point to the parcels directory (the parent of  
the morgencom directory) and run Chandler.

If you don't know what clouds and endpoints are, they are Chandler's  
fancy way of specifying what items are "related" to a given item.  The  
repository cloud API is documented at  
http://o11n.org/docs/current/api/repository.schema.Cloud.Cloud- 
class.html , and since the behavior of the cloud framework has changed  
pretty significantly in the past week, I need to update the wiki docs,  
which I'll try to do soon.
