Add shorthand for creating indexes

[Charizard]

Currently, the creation of an index looks like this,

...
import Lunr from 'ember-cli-lunr/lunr';

export default Controller.extend({
  posts: null,
  init() {
    this._super(...arguments);
    let postsIndex = Lunr.create({ models: get(this, 'posts'), properties: ['title'] });
    set(this, 'postsIndex', postsIndex);
  },
  ...
});

It would be good to invoke this using a shorthand like,

...
import createLunrIndex from 'ember-cli-lunr/lunr-index';

export default Controller.extend({
  posts: null,
  postsIndex: createLunrIndex('posts', ['title'])
  ...
});

Not sure if this is possible though 🤔 ?
