Svelte Zoomable UI

This is a component for providing UI that can zoom into different levels of detail.

More docs coming soon, but you can see an example in this Svelte REPL;

<script>
  let zoomManager;
</script>

<h3><Breadcrumbs {zoomManager} /></h3>
<ZoomableContainer bind:zoomManager>
  {#each data as item}
    <Zoomable id={item.id} title={item.title}>

      ... components that can nest more zoomables
    </Zoomable>
  {/each}
</ZoomableContainer>
