/**
* Build a ContentType object
*
* This method takes the root (a node) of the page's content tree (records from the contents table))
* and transforms it into a corresponding tree of content elements for rendering.
*
* The database fields have the following meaning:
*
* `name` - a page-wide unique name (id) for the element. SHOULD be used as id attribute.
* `content_type` - fully qualified classname of the content element.
* `content_args` - constructor parameters for the content element.
* `component` - name of the entity containing data for the content element.
* `selection` - selection criteria for the data entity.
* `params` - additional parameters for use by the layout file.
*
* @param Content $root
*
* @return ContentTypeInterface[]
