findOwnAddonByName(name) {
    return this.addons.find((addon) => addon.name === name);
  }
Find an addon of the current addon.

Example: ember-data depends on ember-cli-babel and wishes to have
additional control over transpilation this method helps.

```js
// ember-data/index.js
treeForAddon(tree) {
  let babel = this.findOwnAddonByName('ember-cli-babel');

  return babel.transpileTree(tree, {
    // customize the babel step (see: ember-cli-addons readme for more details);
  });
}
```
