removed validate_sample() which was just checking if a sample has Sample_Project and replaced with sample_has_req_keys() which checks that the given sample has a Sample_Name, Sample_Id and Sample_Project. placed the condition checking for Sample_Name == Sample_Id in it's own method to be similar to sample_has_req_keys()
