Word Count

Write a program word_count.py that has the user enter a sentence or a series of words. The program should then call a function count(string) that goes through the string, counts how many words are in that string, and returns that value to the main program.

There are a number of different strategies for counting words in a string. Use these test cases to see how well your function works.
