  Flask will display a warning everytime you startup your application if you are not using it in behind a separate WSGI server.
  
   * Environment: production
   WARNING: Do not use the development server in a production environment.
   Use a production WSGI server instead.
  
  This was not relevant for my scenario and I wanted the message gone,

"""
  print_table will print a structured table with headers, defined column widths, and automatic text wrapping in columns. 
    It will also determine the terminal width and reduce the column widths automatically so they all fit without wrapping outside of the table
  
  print_table requires 3 parameters
    headers: A list or tuple of headers (strings)
    rows:   A list of lists or tuples with table row information as strings
              each entry in inner list maps to a column. 
            For a 3 column table, provide a list of lists or tuples with a length of 3
    sizes:  A list or tuple of integers specifying maximum column width for each column. Must provide a value for each column.
