<!--
  The <search-page-sk> custom element declaration.

  Shows the results of a search request.
  It sends the query string as a JSON request to the
  search entpoint ('/json/search') and renders the result.

  It assumes to the be part of a client site routed system
  of views and therefore offers the 'pageSelected' and 'pageUnselected'
  functions. These need to be called whenever the page goes
  in and out of view.

  Attributes:
    None

  Methods:
    pageSelected(ctx) - Called by the router when the view becomes visible.
          ctx is the context provided in the route dispatch of page.js.

    pageDeselected - Called by the router when the view is no longer visible.

  Events:
    None

  Mailboxes:
    None
