Need: Alias support

snappify: latest
node: 10.11
MacOS

`import {
IDispatch,
IFormsState,
} from '@app/interfaces';`

> The TypeScript props interface contains not supported types:

Solution is use tsconfig.json:

```
paths": {
"@app/*": ["src/app/*"],
```

Also. Does & syntax support?

> Can't find a TypeScript props interface IProps & InjectedFormProps

Thanks for your package!

Feel free to contact.
