Fixed the Kinematic class and updated all classes with a composition
relation. Re-factored all other classes, finished
Basic_Motion_Controller, and debugged system.

Note: Operates, but needs a little tweeking to fine tune the movement of
the turtle and to fix the end condition in the Level object inside
Basic_Motion_Control.java.
Moved all classes in the skelleton package into the structure package,
for less redundancy.
Made extensive changes throughout the project. Fixed problems in the
Kinematic class and got the logic for the Basic_Motion_Movement.update
method.
