Add option to specify output file about gulp-elm HOT 3 CLOSED

At the moment we're using gulp-rename to deal with the name. I think that's a more robust solution, since specifying an output file name won't work if there are multiple input files. Does that make sense to you?

As far as I understand, Elm make can only ever have one output file. Any multiple input files will be compiled into a single output .js or .html. Maybe that assumption is incorrect?

That is correct, but the way that gulp-elm works is that each input file will fire off its own instance of elm-make. If you want multiple files to be compiled together, you can use gulp-elm's bundle function, which does require you to specify an output file name.

If you examine the example in the readme, when the src/ directory contains multiple matching files (e.g. One.elm and Two.elm), the elm task will generate dist/One.js and dist/Two.js, and the elm-bundle task will generate dist/bundle.js.

Let us know if that sounds like it works for you, if you have any suggestions to how the package works or how to clarify the documentation. Hope it helps!
