-; (->> input data file name
-;      read in entire contents
-;      split contents into array of lines
-;      for each line, transform characters '1'/'0' to numbers
-;      build sum array using the lines
-;      convert back to array of characters
-;      join characters into single string
-;      convert binary string to a number (gamma)
-;      multiply gamma by its bit-inverse (bit length hard-coded)
-;      print results
