Clarify difference between this task and `grunt-eslint`

[arthurvr]

There are currently both this task and grunt-eslint (which was created earlier) for the same purpose.

Why did you need to create a new task? (I'm just asking the question, but this should be in the readme too).

Might as well collaborate building one task instead of duplicating work.

Any updates on this? I always used grunt-eslint, but just matter of curiosity, why we have almost similar tasks at the first look of goals and needs. Any thoughts or upcoming collaborations with @sindresorhus ?
