/**
TestDrive:

For this version of TestDrive, we want to allow the user to do as 
much as possible on the site without logging in. So, they should be able 
to do everything but view media, and use the top 'My *' functionality. 
Standards should return national and MCREL standards with a caveat that 
if they were logged in they could get their state standards as well. Search 
should function as well. 

TestDrive doesn't start until they actually try to view some media. They'll get 
nags when they try to access the 'My *' functionallity, but it won't start TestDrive.

Weve recently added an "enhanced" test drive for SSO partner users who haven't yet 
tied their td accounts to their sso accounts. They get the TestDrive interface, but don't have a 
limit on the amount of video they can watch.
