- Now a layer may consist of a path pointing to a directory plus a glob, or a path pointing directly to a single file. - If a file already exists in the database, check if the layer name has changed and if so, update it. - Do not import the actual file contents, as the path is enough (it can be retrieved via the /file/:path API endpoint).
