Function addAddonsToProject

lib/models/blueprint.js:1220–1266

Used to add multiple addons to the project's `package.json` and run their `defaultBlueprint` if they provide one. Generally, this would be done from the `afterInstall` hook, to ensure that a package that is required by a given blueprint is available. @method addAddonsToProject
