Added README explaining why wwmoodleset was created (so that it complies with
Moodle module naming conventions). One substantial difference is that the database
calls in wwmoodleset use ADODB (the global $db database connection supplied by moodle)
rather than using a new database connection DB.pm (PEAR?). In my experience
the latter connection used to access webwork databases was killing the global connection
and calls to moodle databases were failing.
