fun child(path: String): DatasyncNode
Returns a child of this data node specified by a path relative to the data node represented by this DatasyncNode instance.
A child data node represents a location (described by its path) within the tree-like data of a Webcom application and exists independently from the existence of actual data at this path.
The path specifies path segments separated by slashes ("/"), based on the same formalism than the
DatasyncManager.node method.
