charybdis/bin/OTU_CVT_addSampleDescs.R is fragile!

The following line works IF you happen to get superorder as the first column after the samples.
I have to change this string depending on the job.

stopPos <- which(colnames == "superorder") -1

The problem is the variable-number of sample columns with arbitrary naming.
A hacky, but reliable, solution would be an empty column with a delimiting name.
Otherwise, would need to track the number of sample columns between successive scripts: nasty. It is the fact that we are using multiple scripts that makes this complex, but I still like the modular approach overall.

While this is fresh in your head, can you update the script with the empty column solution?
