Rally's fork of Alpakka for akka 2.4

Fork of alpakka compiled with support for akka 2.4/Play 2.5.

Repo	Akka version	Contents
https://github.com/akka/alpakka	2.5.x	everything
https://github.com/AudaxHealthInc/alpakka	2.4.x	subset

Usage

libraryDependencies += "com.rallyhealth" %% "akka-stream-alpakka-csv" % "1.x.y.z"

Motivation

akka versions may not be mixed. Play 2.5 uses akka 2.4 and akka/alpakka dropped support for akka 2.4 in 2017 (akka#624). Upgrading the latest akka version would require updating to a more recent Play version.

Versioning

Uses https://github.com/dwijnand/sbt-dynver, just like alpakka, but with a fourth version number component.

By example:

tag	description
v1.0.0	All tags with only three components come from akka/alpakka.
v1.0.0.1	The first release in AudaxHealthInc/alpakka. Based off of v1.0.0

Subset

This build in this fork only builds modules that we actively support. You may add support for more if you need them and can get them compiling.

The implementations of all modules are still present in the repo to make it easier to take merges from upstream.
