v0.4

This release adds a new possibility to use UnixStream components with the standard Stream API:

• All filters have been extracted in the Predicates class
• All transformers have been extracted in the Functions class

With this refactoring, it is now possible to use UnixStream as a components library 100% compatible with the standard Java Stream API. Here is an example:

Stream.of("1,foo", "2,bar")
        .filter(Predicates.grep("a"))
        .map(Functions.cut(",", 2))
        .forEach(System.out::println);

//prints:
//bar
