Logging use of the C/L billing checker

For some time we’ve recommended that the Cardlock Menu ‘$’ option be used to examine the billing file for unreasonable margins.  Specifically, we think that before any batch is posted, this utility should be run, ranking for cents per gallon profit.  Whether high or low, whatever ranks at the extreme should be viewed as a possible error, perhaps a breakdown in pricing or taxation.  Taking the time to effect this check should prevent some of the credit and rebills we’re asked to assist with.

We are not looking to force anyone to take this step, but we’ve now patched this program to make a log entry that we can examine later.  We can thus prove, after the fact, whether or not this step was included before the posting of any given cardlock batch.
