cannot import an unmodified Scantron rescore file (initial Scantron output file has scores in column named 'score', Scantron re-score output file has the scores in a column named 'test')

If the user reruns the Scantron scoring process after modifying the correct answer source, producing a Scantron rescore file, the column title of the column containing the scores is 'test'. In the initial Scantron output file, the columnn containing the scores is titled 'score'.

When the import process doesn't see the columns named as they are in an initial Scantron file ('student_id', 'last_name', 'first_name', 'initial', 'score') it rejects the file with message "The file loaded does not contain the required header information to load.".

Since the columns in the Scantron rescore file ('student_id', 'last_name', 'first_name', 'initial', 'test') don't match the expected list, the file is rejected.
