Normalization followup to last week

Remember last week when I got too lazy and bored to correctly normalize things in the newspaper column detection stuff?  This is probably the correct normalization.  v1 = col_mean / col_sigma; v2 = (v1 - median(v1))/madsig(v1).  This is essentially centering and whitening the tracer signal from last week (v1 here).
