Early Release

A first release with the bare bones of the package:

• medic(), the central function of the package, clusters medication data by ATC codes and dosage trajectories
• employ(), a central feature, allows for the application of existing clusterings - made by medic() - to new data with a similar structure.
• summary() a summary method with many different characterization options for medic objects
• enrich() a function for adding enriching information to clusterings post-hoc
• refactor() a method for renaming and recoding clusterings made by medic()
• is.medic() a check for both the medic class and the relevant "slots" needed in a medic object
