+function [ GroupedMatrix ] = GetGroupedMatrix( InputMatrix, ratingRow )
+%GroupedMatrix Converts matrix from raw format to concatenated format
+%   Takes an X or Y matrix and ratingRow(which describes how many rows per
+%   nodule) and puts all the data from the related group on the same line
+%   (can be modified if we want 1 1 1 2 2 2 instead of 123 123 123)
