title: is there a state management solution for lit-element?
body: <p>If there is a list which should be rendered from an array, and the array will be passed from the grand-grand-grand-grand-grand-parent custom element. That will be super annoying.</p>
  
  <p>Is there a global state management solution for <code>lit-element</code>, just like <code>redux</code>?</p>
