Write a program that allows a user to type an interactive series of commands which would control the turtle. DEG - Sets the number of degrees (N_deg) which will be used for a future turn (Defaults to 90 if not set)

L - Turns left N_deg degrees (defaults to 90 if DEG not previously called)

R - Turns left N_deg degrees (defaults to 90 if DEG not previously called)

DIST - Sets the distance in pixels (N_dist) which will be used for a future F (forward command) (Defaults to 10 if not set)

F - Moves the turtle forward N_dist number of pixels (Defaults to 10)

RED - Sets the pen to red

BLUE - Sets the pen to blue

GREEN - Sets the pen to green

BLACK - Set the pen to black (the default)

UP - Picks the pen up

DOWN - Puts the pen down
