Revision Log
Abstracted "read directory" functions in SendMail and moved them to Instructor. The instructor calls WeBWorK::Utils::readDirectory and then filters the output according to a pattern match. Sorts as well. Also move read_scoring_file to instructor since it will need to be used in other scripts as well. --Mike
