Prefaced some subroutines with _wwrpc instead of wwmoodleset. These subroutines are internal to wwmoodleset (as far as moodle is concerned) and should eventually be replaced by RPC calls to webwork.
Changed paths:
trunk/wwmoodle/Moodle/wwmoodleset/index.php
trunk/wwmoodle/Moodle/wwmoodleset/lib.php
