load(url, …): Download and store in the class the data loaded from the URL passed as an argument.
save(filename, …) : Save the data on the hard drive.
get_columns_mean() : Return a dictionary with the years as keys and the mean income as values.
get_rows_mean() : Return a dictionary with the counties as keys and the mean income as values.
__str__(): Return a string which when printed should look like the printout in lab 4.
