4958: Hash containing the result of parsing the scanline
4959:
4960: Keys are all proceeded by the string 'scantron.'
4961:
4962: CODE - the CODE in use for this scanline

4965: CODE_ignore_dup - 1 if the CODE is a duplicated use when unique
4966: CODEs were selected, but the usage has been
4967: forced by the operator
4968: ID - student ID
4969: PaperID - if used, the ID number printed on the sheet when the
4970: paper was scanned
4971: FirstName - first name from the sheet
4972: LastName - last name from the sheet
4973:
4974: if just_header was not true these key may also exist
4975:
4976: missingerror - a list of bubbled line numbers that had a blank bubble
4977: that is considered an error (if the operator had already
4978: okayed a blank bubble line as really being blank then
4979: that bubble line number won't appear here.
4980: doubleerror - a list of bubbled line numbers that had more than one
4981: bubble filled in and has not been corrected by the
4982: operator
4983: maxquest - the number of the last bubble line that was parsed
4984:
4985: (<number> starts at 1)
4986: <number>.answer - zero or more letters representing the selected
4987: letters from the scanline for the bubble line
4988: <number>.
4989: if blank there was either no bubble or there where
4990: multiple bubbles, (consult the keys missingerror and
