Rate of change test no fail threshold #93

More of a query. Why is it that ioos_qc.qartod.spike_test takes both a fail threshold and suspect threshold, while ioos_qc.qartod.rate_of_change_test takes only threshold, which flags data as suspect?

I believe that is specified in the QARTOD manuals. My guess is that rate_of_change_test is complicated and can lead to many false positives, while a spike_test is almost a confirmation of the rate_of_change_test failure.
