fun node(path: String): DatasyncNode
Gets a DatasyncNode at a given path.
Path segments are separated by slashes ("/"). The following segments are interpreted this way:
.": current node..": parent node. Note that ".." on the root node has no effect and refers to the root node
itself (contrary to DatasyncNode.parent, which returns null)#{name}", ".hash.{name}": these hashed path-segments automatically expand into 4 segments (the
deepest one being name itself) and make it possible to handle large lists of items
(see Webcom documentation).list.{name}": these path-segments give a hint to the Webcom back end that these nodes are intended to have
many children (as a list) so that it optimises the individual retrieval of their children, preventing
retrieving the nodes as a whole when the data of all their children become too big.
