+=head1 Bubble sheet grading routines
+
+ For this documentation:
+
+ 'scanline' refers to the full line of characters
+ from the file that we are parsing that represents one entire sheet
+
+ 'bubble line' refers to the data
+ representing the line of bubbles that are on the physical bubble sheet
+
+
+The overall process is that a scanned in bubble sheet data is uploaded
+into a course. When a user wants to grade, they select a
+sequence/folder of resources, a file of bubble sheet info, and pick
+one of the predefined configurations for what each scanline looks
+like.
+
+Next each scanline is checked for any errors of either 'missing
+bubbles' (it's an error because it may have been mis-scanned
+because too light bubbling), 'double bubble' (each bubble line should
+have no more that one letter picked), invalid or duplicated CODE,
+invalid student ID
+
+If the CODE option is used that determines the randomization of the
+homework problems, either way the student ID is looked up into a
+username:domain.
+
+During the validation phase the instructor can choose to skip scanlines.
+
+After the validation phase, there are now 3 bubble sheet files
+
+ scantron_original_filename (unmodified original file)
+ scantron_corrected_filename (file where the corrected information has replaced the original information)
+ scantron_skipped_filename (contains the exact text of scanlines that where skipped)
+
+Also there is a separate hash nohist_scantrondata that contains extra
+correction information that isn't representable in the bubble sheet
+file (see &scantron_getfile() for more information)
+
+After all scanlines are either valid, marked as valid or skipped, then
+foreach line foreach problem in the picked sequence, an ssi request is
+made that simulates a user submitting their selected letter(s) against
+the homework problem.
