CVS tags: language_hyphenation_merge, language_hyphenation, HEAD, BZ4492-merge, BZ4492-feature_horizontal_radioresponse, BZ4492-feature_Support_horizontal_radioresponse, BZ4492-Support_horizontal_radioresponse

Using bubblesheets to record grades for handgraded exams
  -- choose what filled last bubble represents (either a zero or max,
     i.e., 5 for 5 bubbles per line, 10 for 10 bubbles per line etc.)
grades.pm
  - New routine: &hand_bubble_option() determines if sequence to be graded
    contains response types which are handgraded, and offers radio buttons to
    choose score for last bubble.
response.pm
  - &repetition() routine can be called in scalar context of in array context.
    scalar: returns number of lines to encode weight
    array: returns (number of lines to encode weight, bubbles/line).
chemresponse.pm imageresponse.pm caparesponse/caparesponse.pm
  - &response::repetition() now explicitly called in scalar context.
Work in progress.
  (Corresponding option needed in lonprintout.pm to set
   correct number of bubble rows for handgraded questions with
   weight >= bubbles per row).
