First iteration of incorporating the SEOMoz classes
Amended and tidied up a lot of the SEOMoz files, commit before moving
the SEOMoz url metrics (PA and DA) out of the class URLPlusDataPoints.
Created all required entities for database, minor changes to index.html,
now performs basic insert to urls.url table.
Basic write to url table functionality works. Tidied up styles.css and
removed unnec refs....
Altered GoFetchServlet so that it now uses JPA to write to DB.
This version writes to server DB successfully - error in not registering
app id with database.
Added JS user input validation, 
adjusted persistence.xml to allow deployed app to connect to DB.
added robots.txt to stop alexa robot causing null exception when
crawling site.
Adjusted id's of all entities to make them unique.
Added JQPL to get all URLs from DB that were added today and yesterday
Added check to make sure url entered by user does not already exist in
DB
Added server side user entry validation to GoFetchServlet.
Added check to make sure url entered is not already in the DB.
Added basic SEOMoz backlinks functionality. Backlinks to target are now
got from SEOMoz server and added to the url's table.
App now retrieves backlink data from SEOMoz server and saves all
backlinks to url table and their links relationship to target in links
table.
This is the action that will be performed at 00:01 every day on
yesterdays target urls.
Moved the pa and da columns from seomoz_data to url table in schema -
should make DB read/writes more efficient.
Added get page and domain authority and persist these to DB for each
target url.
Had to add SEOMoz server delay outside of SEOMoz implementation code -
and into servlet code.
Now have all code - untested - to retrieve all PA and DA for target's
and unique domains.
Doc title can only be 45 chars long.
Updated the database schema
Changed the API to get social data from to sharedcount.com - this
returns all the social data we want in one call.
Added Testing documentation.doc.
Updated SQL schema to take into account multi-target urls.
Only urls that point to final target url, AND that DO NOT link as target
or source in any other links will be deleted.
All links in the tree with final target url will be deleted.
All social and other data associated with each url will be deleted.
updated sql to login not using root.
updated index.html
updated schema and made logging work on GAE.
