Turtle R7RS

This library is for turtle graphics implemented in R7RS Scheme. Because there is no portable way to implement graphics, the code was made modular enough to have multiple front-ends. For Gauche, gauche-tk is used. For Kawa, the built-in HTTP server is used to send instructions to a browser front-end.

YASOS is a dependency to allow extending the turtle.
