MVP v5: Core App

[paulpestov]

For showcasing the app it is necessary to implement a core behaviour of rendering collection panels and displaying content.

AC:

• Given a basic configuration, the app should pick it up and render the panels accordingly
• Each panel takes a TextAPI collection URL and renders a single item from that collection
• Each panel behaves as a indivual instance and as per default has no dependancy to any other panel
• There is a switch to change different views in which the panel can display the content
  • PIP-Mode: The text is shown as a base layer and a small preview of the image is hovering in the corner. By clicking the preview image the layer switch and the image now is shown as the base layer and the text is shown in the preview
  • Text-Only: Only the text is shown
  • Side-By-Side: Text and Image are shown equally next to each other
  • Image-Only: Only the image is shown
• The collection title is visible in the left upper corner
• The manifest + item titles are shown as main headline above the text
• Navigation buttons are visible and paginate through items/manifests within the selected collection
• Below the headline there is a switch to toggle given content types
• Any change to the navigation or content type will be reflected to text AND image simultanoeusly
