BZ 4074 (incomplete) Modify scantron_get_maxbubble
- Analyze each resource to determine how many lines on the bubble
sheet were actually required using the new bubble_lines
analysis hash entry.
- Create a hash of resource->symb().part_id for each part in the
set that describes the answer sheet lines required for each part on the
exam.
- Return the total number of answer sheet lines required as per the analysis
output.

4417: =head1 Bubble sheet grading routines
4418:
4419: For this documentation:
4420:
4421: 'scanline' refers to the full line of characters
4422: from the file that we are parsing that represents one entire sheet
4423:
4424: 'bubble line' refers to the data
4425: representing the line of bubbles that are on the physical bubble sheet
4426:
4427:
4428: The overall process is that a scanned in bubble sheet data is uploaded
4429: into a course. When a user wants to grade, they select a
4430: sequence/folder of resources, a file of bubble sheet info, and pick
4431: one of the predefined configurations for what each scanline looks
4432: like.
4433:
4434: Next each scanline is checked for any errors of either 'missing
4435: bubbles' (it's an error because it may have been mis-scanned
4436: because too light bubbling), 'double bubble' (each bubble line should
4437: have no more that one letter picked), invalid or duplicated CODE,
4438: invalid student ID
4439:
4440: If the CODE option is used that determines the randomization of the
4441: homework problems, either way the student ID is looked up into a
4442: username:domain.
4443:
4444: During the validation phase the instructor can choose to skip scanlines.
4445:
4446: After the validation phase, there are now 3 bubble sheet files
4447:
4448: scantron_original_filename (unmodified original file)
4449: scantron_corrected_filename (file where the corrected information has replaced the original information)
4450: scantron_skipped_filename (contains the exact text of scanlines that where skipped)
4451:
4452: Also there is a separate hash nohist_scantrondata that contains extra
4453: correction information that isn't representable in the bubble sheet
4454: file (see &scantron_getfile() for more information)
4455:
4456: After all scanlines are either valid, marked as valid or skipped, then
4457: foreach line foreach problem in the picked sequence, an ssi request is
4458: made that simulates a user submitting their selected letter(s) against
4459: the homework problem.
