Description

This function takes a dataframe, and does a simple check for outliers based on the boxplot.stats() routine. Specifically, it identifies data which is 1.5, 5, or 10 times the length of the box away from the box. These are identified as "Possible", "Likely", or "Extreme" in the resultant "OL_<field>" column, respectively. Other data is identified as "OK", which indicates that it is within a reasonable range of the mean.
