Summary:
This PR allows anyone to publish templates for React Native.
It's possible for people to publish modules for React Native, we should also support custom templates. A suggestion from a Cordova mantainer where they did the same thing suggests this is useful:
https://github.com/mkonicek/AppTemplateFeedback/issues/1
I published a sample template [react-native-template-demo](https://www.npmjs.com/package/react-native-template-demo).
(GitHub: https://github.com/mkonicek/react-native-template-demo)
With this PR anyone can then use that template:
`react-native init MyApp --template demo`
The convention is: if someone publishes an npm package called `react-native-template-foo`, people can use it by running `react-native init MyApp --template foo`.
Use a template called `react-native-template-demo` from npm:
`react-native init MyApp --template demo`
Use a local template:
`react-native init MyApp --template file:///path_to/react-native-template-dem
