Extend from tslint/recommended and remove duplicate rules

[the-ult]

Would be nice if tslint-angular would extend from tslint:recommended and remove the duplicate rules.

Or.

• Remove the duplicate rules and add it as best practice to the readme?

{
"extends": [
    "tslint:recommended",   // Should be extended before tslint-angular
    "tslint-angular",
     ....
  ]
}
