Program sudumptrace dumps each trace's amplitude values in
separate columns. The first column is a sample counter; the
second column is the sample time.

Above each trace are the values of the keys the user chose
to print. The name of each key is above the column of sample
times.

Below is the output of demo script dumptrace.sh
