/**
* This activity demonstrates the use of Path trimming and its use in animations.
* The trim method works by extracting just a portion of the Path relative to its
* length. By modifying the offset of the trim, we can make the trim path span
* the start and end. In this demo, the line segment appears to be traversing
* a circle.
