auto-detecting watchman about sane

[amasad]

It should be easy to add an auto option to the sane() function that chooses the best thing available. I worry about making it the default and tell people that it will always do the right thing.

[stefanpenner]

It's fine to not make auto the default here, but let consumers of this library make that choice.
e.g.

sane.autoWatch('...');

It would also be nice if we where provided with a way to see which watcher auto choose.

[stefanpenner]

ultimately, this isn't a blocker for me merely a thought.

@stefanpenner Today, a few years later, would it make sense to merge watch-detector (https://github.com/chrmod/watch-detector/) with this repo?

I'm working on updates to the docs for ember-cli and wanted to see if the 'missing watchman' console message had changed. I had to dig a bit to find it:

1. I checked ember-cli source, noticed that watching is handled by broccoli.
2. Found broccoli-sane-watcher, saw that it's merged into broccoli core.
3. Checked broccoli core, saw that it used watch-detector.

I know this is how the NPM ecosystem works, everything is broken down into atoms and spread over multiple packages. 😄 But sometimes it would be easier if these were at least collected under the same namespace (e.g. @sane/core, @sane/watch-detector).

Since you've already suggested adding watch-detection to sane (this old issue) and now seem to have commit rights to the repo, I just wanted to hear your thoughts on this!
