[Dev-flock] sources and citations added to staging

[Lucy Mendel]

yo,

Just a heads up: I added sources, citations and articles to staging
(http://staging.thoughtandmemory.org/Main)

Source = A Node with NodeType "Source". Any organization or person
that "publishes" "articles" (terms used loosely :-)
Article = new model. These reference articles and media published by the source
Citation = many-to-many link between Behaviors (aka reviews) and Articles.

For an example check out

     http://staging.thoughtandmemory.org/Main/node/390/

See how there is a citation on the first review? Try adding citations
for the other reviews-- you can select the Ethiscore source since it
already exists. you can also select the Mars report article published
in Ethiscore, if that applies to multiple reviews.

Try creating a review--now you can give the citation then and there.
Right now it is not optional. Should be?

Try clicking on the Ethiscore source. See how it is just a node like
any other? Except the template checks for if the node has the "Source"
NodeType, and if so, it shows the Articles associated with that node.

Whoa, the UI needs help. Anyone interested in doing some html/css/js?
For instance, clicking on an existing source should use ajax to populate
the existing articles for that source.

Let me know if you have an problems or feedback. I'm going to add this
to the API. Pepe-- this should help you. I also added login and registration
internal APIs, but I think now that we have sources we don't need
users-as-sources so I'm not going to externalize that. Yeah?

cheers,
Lucy.
