As a SPA developer, I can create a SPA which can load content from different Magnolia pages, depending on the url route, so that I can fulfill a 'website-like' SPA requirement.

It should be possible for an SPA to get its content from a Magnolia page, or its subpages.

Acceptance Criteria:

• Demo project: React SPA loads necessary content and templates from one magnolia page based on the url (routing).
• Demo project: React demo illustrates a simple dynamic navigation based on nested subpages in Magnolia Page Editor. Need only support two levels of depth.

(AC can be satisfied by simple demo project, possibly no development on the SPA helper libraries is necessary.)

Optional: This demo project could be used, it has sample content including two levels of depth, and a navigation component & endpoint. (sample content in the _dev directory) https://github.com/magnolia-community/react-area51-alpha/tree/master/mag-aliens-demo
