final submission number words problem sentences

I was able to add the remaining numbers above 1000 without too much
difficulty. As I worked, I used number.py to test the numbers, which
helped correct errors early on and I didn’t have too many issues. I
think the planning really helped with this problem set. I only ran into
2 problems while debugging with test_numberwords.py. The first was not
including the word “and”, which was an easy fix. The second turned out
to be an error in test_numberwords.py as one of the numbers 588567 did
not match the english type. I changed the number to 589567 in the test
program which fixed that error. This problem set was one of the easier
assignments for me.
