Change the main() function:

def main(data):
    """
    Get the latex source; return a raw string for the webserver to send to the client
    
    Take the outgoing HTML and turn it into a python object.  Search the object for the
    <div> and <span> tags that indicate latex source -- the tags we can handle are given
    in the global variable TYPES.  If there isn't anything to handle, return.  If there is, 
    process it and return a pretty-ied raw string of HTML for the webserver to send to the client.
    
    Notes:  A working directory must be set via os.chdir so latex knows where to put its output
    """
    if not os.path.isdir(TEMPDIR):
        os.mkdir(TEMPDIR, 0755)
    os.chdir(TEMPDIR)
    soup = BeautifulSoup(data)
    equations = soup.fetch(TYPES)
    if not equations:
        # return
        return data # <--------------------------------------

In other words, if there are no embedded equations, return the original
page content as is.
