The xCDL Metadata

Work in progress.

The xCDL metadata is a set of definitions used by xcdl to drive the configuration process.

These definitions are stored in the xcdl.json file located in the project top's folder, as well as in other possible JSON files located in subfolders.

The top folder's xcdl.json file must define a cdlPackage object.
