    description:
            This code looks at an animation od selected node/object
            and sets the animationa and playback to whatever the range
            of the first and the last keyframes are.


    warning:
        that code may destroy any of your project.
        This code is wont be a risc of your projects as is comment lines is longer than the code.
        This is very innocent code.if something bad happens recheck yourself.


    notes:
       I tested that code should work any of maya version 7 and after.
       Did not check for earlier


    special thanks: Mr. Robinson for constantly pushing me ......
