the first part of part b of homework 2 was downloaded from a ZIP file at http://aws.amazon.com/code/JavaScript/2609
tested some code to submit a request and receive a response with XML in the browser
my changes to the code to make it work for this assignment
the previous commit did not have the part_b.js file, but now all the Javascript that was in the index.html is now in the part_b.js file rather than in the html file
renamed the jssha2 directory to js and moved the part_b.js file to the js directory
some cosmetics to the HTML interface
