get https://api2.pennsieve.io/metadata/package
This method returns all metadata records associated with the package.
It includes the record that associated with the package, and all metadata records that are hierarchically parents of the associated record.
For example, consider three models (Patient, Visit, Sample) where Patient has a relationship to Visit and Visit has a relationship to Sample. If a file is associated with a Sample record, this methods returns the sample, visit and patient metadata.
Note that the direction of the relationship is important and only relationships "upstream" are returned. This includes records that have a property that points to another record.
