[ShaiberAlon]

It would be nice to create a combine table for all reports to show the stats for samples.

It should be pretty straight forward, all that is needed is to turn this:

number of pairs analyzed      : 6351369
total pairs passed            : 5923040 (%93.26 of all pairs)
  total pair_1 trimmed        : 463627 (%7.83 of all passed pairs)
  total pair_2 trimmed        : 343364 (%5.80 of all passed pairs)
total pairs failed            : 428329 (%6.74 of all pairs)
  pairs failed due to pair_1  : 66495 (%15.52 of all failed pairs)
  pairs failed due to pair_2  : 269475 (%62.91 of all failed pairs)
  pairs failed due to both    : 92359 (%21.56 of all failed pairs)
  FAILED_REASON_P             : 67299 (%15.71 of all failed pairs)
  FAILED_REASON_N             : 24921 (%5.82 of all failed pairs)

To a column wise output (whenever both are available, keep only the percentage)
