/** Computes a matrix of distances between all genotypes in the specified
    .gen file, using the matching and measure weights as specified in the
    command line.

    Command line parameters: [-names] <genotypesFile> <w_dP> <w_dDEG> <w_dNEU> <w_dGEO>

    Parameters:
      <genotypesFile> name of a file with genotypes
      <w_dP> weight of the difference in the number of parts
      <w_dDEG> weight of the difference in degrees of matched parts
      <w_dNEU> weight of the difference in neurons of matched parts
      <w_dGEO> weight of the distance between matched parts

    Switches:
      -names specifies that the number and names of genotypes are to be printed to output
        before the distance matrix; by default the number and names are not printed

    Outputs a distance matrix in the format:
    <row_1> (columns in a row are separated by TABs)
    ...
    <row_n>
