USER VISIBLE CHANGES

    o ch2locs (retrievable via dsQTL::getSNPlocs) has been changed at about 1850 locations
      where rs numbers had been associated with hg19 addresses; the dsQTL regions are hg18
      as are all the chr2... SNP addresses.  Previously the discoverable rs numbers used
      in the Chicago distribution from http://eqtl.uchicago.edu/dsQTL_data/GENOTYPES/ had
      be mapped via SNPlocs...20111119, but now they come directly from the Chicago text file.
