- Bug 5596.
Add a routine to lonnet.pm -- get_multiple_instusers() which makes one call
to lond > lonsql > localenroll.pm to retrieve institutional data
for multiple users when adding users via file upload, to minimize number
of sleep() commands needed. Supports up to 1s per query, on localenroll.pm
side if adding more than 100 new users.
- Add new routine to localenroll.pm -- &get_multusersinfo() -- to retrieve
institutional data for users being added via user file upload.
Note: if this routine does not exist in localenroll.pm, will fall-back
to retrieving institutional data using a separate call to &get_userinfo()
for each user.
