=head1 SYNOPSIS
Coordinates the response to clicking an image.
This is part of the LearningOnline Network with CAPA project
described at http://www.lon-capa.org.
=head1 SUBROUTINES
=over
Little texts
=item initlittle()
=item menubuttons()
This gets called at the top of the body section
=item show_return_link()
=item registerurl()
This gets called in the header section
=item innerregister()
This gets called in order to register a URL, both with the Remote
and in the body of the document
=item loadevents()
=item unloadevents()
=item startupremote()
=item setflags()
=item maincall()
=item load_remote_msg()
=item get_menu_name()
=item reopenmenu()
=item open()
Open the menu
=item clear()
=item switch()
Switch a button or create a link
Switch acts on the javascript that is executed when a button is clicked.
The javascript is usually similar to "go('/adm/roles')" or "cstrgo(..)".
