Investigate if it is possible to define constants such as [DataType](https://github.com/G-Node/nix-java/blob/master/src/main/java/org/g_node/nix/DataType.java) as java enums. It should be further investigated whether it is really necessary to redefine constants already defined by the NIX library.
