This element provides a timeline that can be used for playback, keyframe
position visualization, and more!
Also added light testing code before the more major refactor of data
into the Project itself rather than being handled so directly by the
animations or elements tree modules (and other modules soon enough).
CatAnimation struct provides an interface for accessing, changing,
and removing CSS animations and keyframes. It provides a more
JavaScript programming friendly interface by using basic Objects
to represent keyframes and their properties.
Add functionality to properly set the tree heads and rows outside
of the rather hackish build from DOM method.
The animations tree module and accompanying HTML provides a means
to select, add, and delete animations stored in the project HTML
file. It is incomplete as of yet.
Additionally, fixed a minor bug in Cat's emit method that made all
functions that returned a non-truthy value (such as no return) to
abort all proceeding listeners.
