Training and testing split

Given a vector of subject_id and a threshold, returns a list of which members should be in the training set and which should be in the testing set. The function relies on whether or not the absolute value of the Jenkins's one_at_a_time hash function exceeds the maximum possible value (2147483647) multiplied by the threshold.
