+% prd=dftoperiod(d,b,t) - estimate period from difference function
+%
+%  prd: row matrix of period estimates
+%
+%  d: column vector or matrix of difference functions
+%  b: bounds matrix ([lo, hi])
+%  t: threshold
+%
+% Difference functions are supposed to be cumulative-mean-normalized.
+% For each column of d, search for the first minimum between lo and hi that
+% falls below threshold.  The index of this minimum (re 0) 
+% is the period estimate.
