Fixed up loadXML. Now puts student names and psuedo names into lists. Uses static variables now, though that might be a bad idea. Was having issues with 2D arrays only to find out that Java doesn't handle arrays how I thought. Decided to use ArrayLists instead. Can write iterator to put Names and PsuedoNames into same data structure. Not sure if we should split up first and last names, it doesn't seem to have a purpose to me.
Added the ability to load assignments, including their category and grades for every student. Also update the example XML file.
