## readURClassList
##
## this is a specific routine for reading class lists which come from the registrar's
## office at the Univ of Rochesterand producing a classlist file usable by WeBWorK

## IT IS ASSUMED THAT THE REGISTRAR'S LIST IS DELIMITED WITH SEMICOLONS (;)

##
## Takes three parameters.
## First, the full file name of the Registrar's class list file with the header
##	material stripped off.
## Second, the full file name of the output WeBWorK classlist file
## Third, the name of the section, e.g. Pizer or "Gage MWF" or "" (blank).
##   For example classlist files from multiple sections can be concatonated
##   one large classlist file for a whole multisection course
##
## NOTE:  Be very careful.  The registrar's file may get corrupted by e-mail.
