'''
Write a program that reads a matrix of numbers separated by newlines
and whitespace, like this:
10 5 4 20
9 33 27 16
11 6 55 3
then calculates the sums for each row and column, optionally outputting them...
Rows: 39 85 75
Columns: 30 44 86 39
then prints two new matrices:
first, print the matrix with its rows sorted by their sums
then, print the matrix with its columns sorted by their sums.
Like this:
10 5 4 20
11 6 55 3
9 33 27 16
10 20 5 4
9 16 33 27
11 3 6 55
Here's a large input matrix to test your program on.

For bonus points, format your output matrices nicely
(align the columns, draw boxes with - and |...)
