Data entry wizard

[evz]

After examining the documents that Tony shared with us regarding the existing data entry workflow, we decided to take slightly different approach on how to get information into the CMS which involves a guided data entry wizard. Since everything in the system ultimately starts with a source (and most everything is attached to a source), we decided to have things cascade from there and take the following steps (I've made this a checklist to show what we have roughed out so far):

• [x] Step 1: Describe the source itself.
• [x] Step 2: Describe organizations.
• [x] Step 3: Describe people and tell us what organizations they belong to.
• [x] Step 4: Describe the relationship between the people and the organizations (so, for instance, what rank do they have, what is their title, etc)
• [x] Step 5: Describe Sites and Areas from the source and associate them with organizations.
• [x] Step 6: Describe any events mentioned in the source.

This assumes a pretty radical departure from what existed in the CMS previously and is obviously open for revision.

We'll also need the ability to modify or add to entities extracted from a source.
