This example shows how to edit a labeling schedule by modifying pairs.

The showuniquepairs command shows the unique pairs in the sequence.
 On invocation all pairs are listed. It is shown how many times a 
pair occurs in the included sequence and how many times it appears 
in the whole sequence. The shortcut "banscramble" automatically bans
 PRO, ASP, ASN, GLU and GLN.

There are ten slots for labeling schemes, 5 of which are shown with 
the showmultiple command side by side. With the copyschedule schedules 
can be saved before or after editing with modifypair. The sched argument
 to modifypair codes for a labeling pattern. Since there are 2^samples 
labeling patterns the schedule pattern is described by a number ranging
 from 1 to 2^samples. For example the pattern X-X would be expressed by 
the number 5. The rank specifies the slot where the labeling should be edited.

The calculation is in the file tst_score.cya.
