Not quite cosmic turtle

This is a sequence of turtle pages that build on each other.

The pages have hints which should help.

Last Release with TurtleTypes

Until now we specified which turtle to use based on TurtleType - for now I've removed TurtleType and tried to simplify the turtle. I'm sure we'll go back and forth on some of this.

Also, josephlord suggested a nice introductory activity using targets so the next version includes targets.

On the other hand, I did want to capture this version as a release so here it is.

Thank you all for your feedback and help.

Pre WWDC2015 Release

The Turtle is now more of a controller with paths, an avatar and a view. Note the Turtle, path, and avatar are implemented as Structs. The View is a subclass of UIView and can't be a struct.

First beta release

The functionality for the user is sufficient for an initial release.

I'm not happy with the underlying architecture - so we'll create a branch and work on that next.
