    # A Resque job that allows for generation of randomized patients by a Resque worker. Can be created as follows:
    #
    #    QME::Randomizer::PatientRandomizationJob.create(:template_dir => '/xx/yy', :count => 100, [:test_id => ObjectId])
    #
    # This will return a uuid which can be used to check in on the status of a job. More details on this can be found
    # at the {Resque Stats project page}[https://github.com/quirkey/resque-status].
