pricelimits

PRICELIMITS  Fills in a struct with default values for offer/bid limits.
   LIM = PRICELIMITS(LIM, HAVEQ)
   The final structure looks like:
       LIM.P.min_bid           - bids below this are withheld
            .max_offer         - offers above this are withheld
            .min_cleared_bid   - cleared bid prices below this are clipped
            .max_cleared_offer - cleared offer prices above this are clipped
          .Q       (optional, same structure as P)

0001 function lim = pricelimits(lim, haveQ)
