Flux, composable streaming abstractions with Miou

Flux is a library that implements a bounded queue as well as several abstractions related to streams. It can take advantage of parallelisation as proposed by Miou (with Miou.call), but also of the concept of ownership (see Miou.Ownership) related to resources (such as file descriptors).

The advantage of flux is that it facilitates the composition of streams in order to share information flux between tasks.
