  Rosalind helpers for http://rosalind.info

  Works best with minimake utility.

  Available features:
    rosalind_sample [file[.cpp]]    : download sample input
    rosalind_expected [file[.cpp]]  : show expected output for sample input
    rosalind_setup [file[.cpp]]     : download sample, setup minimake default
                                      and prepare stub .cpp file (if not present)
    rosalind_refresh                : reload helpers
    rosalind_clean                  : unload helpers

  All funtions can be used with minimake default variable.

  Helpers are defined in $rosalind_SOURCE
