Returns an array containing lines from the scantron format file for
the domain of the course.

If a url for a custom.tab file is listed in domain's configuration.db,
lines are from this file.

Otherwise, if a default.tab has been published in RES space by the
domainconfig user, lines are from this file.

Otherwise, fall back to getting lines from the legacy file on the
local server: /home/httpd/lonTabs/default_scantronformat.tab

=item get_scantron_config

Parse and return the scantron configuration line selected as a
hash of configuration file fields.

Arguments:
which - the name of the configuration to parse from the file.


Returns:
If the named configuration is not in the file, an empty
hash is returned.
a hash with the fields
name - internal name for the this configuration setup
description - text to display to operator that describes this config
CODElocation - if 0 or the string 'none'
- no CODE exists for this config
if -1 \|\| the string 'letter'
- a CODE exists for this config and is
a string of letters
Unsupported value (but planned for future support)
if a positive integer
- The CODE exists as the first n items from
the question section of the form
if the string 'number'
- The CODE exists for this config and is
a string of numbers
CODEstart - (only matter if a CODE exists) column in the line where
the CODE starts
CODElength - length of the CODE
IDstart - column where the student/employee ID starts
IDlength - length of the student/employee ID info
Qstart - column where the information from the bubbled
'questions' start
Qlength - number of columns comprising a single bubble line from
the sheet. (usually either 1 or 10)
Qon - either a single character representing the character used
to signal a bubble was chosen in the positional setup, or
the string 'letter' if the letter of the chosen bubble is
in the final, or 'number' if a number representing the
chosen bubble is in the file (1->A 0->J)
Qoff - the character used to represent that a bubble was
left blank
PaperID - if the scanning process generates a unique number for each
sheet scanned the column that this ID number starts in
PaperIDlength - number of columns that comprise the unique ID number
for the sheet of paper
FirstName - column that the first name starts in
FirstNameLength - number of columns that the first name spans

LastName - column that the last name starts in
LastNameLength - number of columns that the last name spans
BubblesPerRow - number of bubbles available in each row used to
bubble an answer. (If not specified, 10 assumed).
