`hax-ce-context`
A context menu that provides common custom-element based authoring options. While
trying to call for haxProperties which can automatically generate the buttons
required for populating input.

@demo demo/index.html

@microcopy - the mental model for this element
 - context menu - this is a menu of custom-element based buttons and events for use in a larger solution.
