// PSEUDO-CODE
// - Use read_line_vals method to search through file until finds a line starting with header
// - Read each item in the line into an array of ints, using comma delimiters to separate
// - Run whatever test is needed on the array to ensure that all the values are valid
// - Usually something like counting the instances of each number to ensure correct permutation
// - Repeat for all headers
