[AgileWiki] The NoGuests DEnt, SimpleAccounting

[Bill la F. <bil...@su...>]

Prior to generating the display for a rolon, the User Interface Model 
(UIM) now first checks to see if the NoGuests Descriptor Entry has been 
set. If it has been set and the user name is "Guest" (i.e. the user has 
not logged in), then instead of the document being displayed, a message 
is given directing the user to login or register before proceeding. 
(Links for these commands are also provided.)

Now remember that a Ledger Entry in a Rolon's Descriptor Unit has the 
same effect as having a Descriptor Entry in the Rolon itself.

This behavior has been requested as part of an application I am working 
on for Sun Microsystems (i.e. my day job). However, it seems appripriate 
for any application rolon. Consequently I've now changed the deploy for 
SimpleAccounting to set this LEnt in the SimpleAccountingDescriptorUnit.

I'll note that I've also updated the documentation for DEnts and LEnts 
at agilewiki.org.
