This program repeatedly prompts the user for guesses until
they correctly guess the Point the computer is thinking of.

EXPECTED OUTPUT:

I'm thinking of a point somewhere
between (1, 1) and (5, 5) ...
It is 4.47213595499958 from the origin.

what is your x and y? 1 1
right up
what is your x and y? 5 1
left up
what is your x and y? 3 2
right
what is your x and y? 4 2
you guessed it!
