-Added ability to send a request to the server and receive a response.  Once that response is received parses it and displays a particular row of information in a list view. (Users for now). *Note: This will have to move to another location in the app, users should not be displayed within the Decrees activity.
-Added a RequestTask class, which is an AsyncTask to communicate with the server.
-Added an interface to grab the response from the AsyncTask so it can be used in other activities.
