make_summary reformat

[necrolyte2]

After discussing with @demis001 we think it will be best to reformat the make_summary output such that the unassembled reads section is put beneath the contigs section and the numReads is aligned with both.
These changes would allow for investigators to easily sort/filter via the command line and in excel

• ctg# field would be removed
• Unassembled reads would still be grouped by the --group-by column
• The project/sample name column for each line would then be concatenated with the contig name
  • For unassembled reads the same would occur, however, each line would get it's own identifier number(aka, the first unassembled line would be ur1, the second would be ur2)
• All other columns would be removed from the report and could be gathered by the user or another script very easily such as grep '.' projectdir/results/*/*.count
  • For more detailed stats like N50, we could generate a separate very high level summary that contains all of the info(Related Coverage statistics for makesummary output #30)
