def write_data_csv(mat_file, csv_file):
'''
Creates CSV spreadsheet for automated breast segmentation provided the segmentation data MATLAB output file.
If the spreadsheet does not exist at runtime, it will be created. If the spreadsheet does exist, then it is
appended to.
NOTE: This function requires the mat73 module - as this reads MATLAB structures produced by MATLAB v7.3+.
See the github page for further details: https://github.com/skjerns/mat7.3
Arguments:
mat_file (MATLAB .mat file): Segmentation data MATLAB output file (from DeepSeA)
csv_file (csv file): Output csv filename (with extension)
Returns:
csv_file (csv file): Output csv filename (with extension) with appended data/information
