Progress

I'm continuing to work on www.mathtestnow.com.  Today I've mainly been focusing on cosmetic changes and getting the site indexed.  Here are a few specifics:

• Allow users to switch from the logon page to the registration page without doing a page refresh.  Changes were made here: www.mathtestnow.com/user/index.php
• Fixed a problem where the most recently added equation was not formatted by MathJax.  Added a pause after updating the AngularJS model but before calling the MathJax.
• Trying to make it easier to understand what you are supposed to do when you come to the test creation page.  Previously you can only see one dropdown, but I changed it so that there is a pre-selected option... I think that makes it clearer how the thing works.
