Summary

See #4 (closed). We now use Julia enums for data types, roles, importances, and collections (currently only LIST). Also, value and datatype setters and getters now operate on the Extern C structs directly.

Focus

A lot of changes due to the introduction of the new structs _Value and _DataType in Entity.jl. All in all, this simplified the remaining code since some repetitions could be removed (e.g., if-cases in set_value and set_datatype). The new enums have been added to Constants.jl.

Test Environment

Unit and integration tests should be sufficient but feel free to test setting and getting of values and datatypes interactively, too.
