Added support for Namaste style metadata about collection (type, who, what, when, where, version and contact). The metadata is stored in the `collection.json` and Namaste are rended on `SaveMetadata()` calls. `SaveMetadata()` is now an exported function. There is now a concept of "dataset_version" versus "version". "version" is the semvar assoc...

Using a "grid" of collection data is useful when sorting ...
