Haxe's JavaScript exports everything in a Haxe compilation into a single output file. This is great for building applications. For a general purpose library, however, it would be nice if it output a `*.js` file per `*.hx` file within my compiled sources. 

The intent of this is so that I can create a NodeJs module where the consumer of the library only needs to `require()` the particular files that they would like to use. Is this currently possible using the Haxe compiler on its own, or via an external tool?
