XML Parser nearly integrated

I was able to gut out the code that David has added and place the XML
parser where it used to deal with hardcoded information. I am slowly
removing the Trial object itself and going for a more contained
solution. I still need to figure out how to deal with the “res” and
“lim” fields, how to get the link working, get search working, get
filter working, get the share button working, and finally work on the
UI so that it is more user-friendly.
