# App: File Browser

# Author: Matt Giuca

# Date: 9/1/2008

# The file browser application. Presents an Ajax-based interface to the

# student's subversion workspace.

# Note that there is virtually no server-side code for this application. It

# simply presents static HTML and JavaScript, and all server-side activities

# take place in the FileService app (for handling Ajax requests).
