Another housekeeping release to fix the demo page on webcomponents.org.

This is a housekeeping release that introduces a functioning demo, a lighter npm package and some internal documentation improvements..

This release packs a new method, .refresh() that makes the element recollect the position of all children. This is necessary in cases where the element was hidden from the DOM and then unhidden.

This release removes most of the properties on the element itself and allows customizing the applied transitions through the --transition CSS variable.

This release changes the default easing function to ease-out.

This release introduces actual properties to the element so that it can now be used with property-setting template engines (like lit-html's extended or Polymer without $ sign).

This release contains various small bugfixes, performance and timing improvements.

This release changes the default class name applied to transitioning elements to prevent collisions.
