upp returns a vector of length k equal to the net UPP for the
merging parties' products and 0 for all other products.
An instance of one of the classes listed above.
upp uses the results from the merger simulation and
calibration to compute the upwards pricing pressure of the merger on
each merging parties' products.
upp.bertrand calculates net UPP
without the need to first calibrate a demand system and simulate a merger.
