v2.0.0-beta.18 (#345)
* feat(populate): `childAlias` for store results of populate on another parameter - #126 * feat(profile): Firestore support for `updateProfile` method - [issue 25 on redux-firestore](prescottprue/redux-firestore#25) * feat(storage): `progress` option added to `uploadFile` method - #346 * feat(storage): `uploadFile` default metadata written to DB now includes `createdAt` * feat(core): `redux-firestore` is no longer a dependency - managed by library user directly * fix(examples): Material-ui example updates (including moving `injectTapEventPlugin()` to `main.js`)

**Queries Based On Props**

It is common to make a detail page that loads a single item instead of a whole list of items. A query for a specific `Todos` can be created using

### Object's Parameter
176+
### Place Result On Another Parameter {#childAlias}
177+
178+
There is also the option to place the results of a populate on another parameter instead of replacing the original child (i.e. "alias" the child result). An example of this could be populating the `owner` parameter onto the `ownerObj` parameter, which would leave the `owner` parameter intact (since the child from the populate was "aliased" to `ownerObj`).

For more details including the initial feature request, checkout [issue #126](https://github.com/prescottprue/react-redux-firebase/issues/126).

```javascript
184+
const populates = [
185+
{ child: 'owner', root: 'users', childAlias: 'ownerObj' }
