We recommend using `initWithDefaults` and we should follow the recommendation. This change removes all usage of `init` within MDC components in order to let us remove that initializer from the public surface.

We need to add @objc annotations to colorScheme and typographyScheme instances in our Swift examples, because we moved to Swift 4.2, the respondsToSelector won't find `setColorScheme:` and `setTypographyScheme:` setters otherwise.
This is a follow up PR for #7166 adds @objc annotations to Swift catalogMetadata() methods, because the Swift 4 compiler no longer attempts to infer what methods should be visible to Objective-C. As a result of this change in the compiler, no Swift examples were showing up in Dragons after #7166. See this article: https://useyourloaf.com/blog/objc-warnings-upgrading-to-swift-4/ for additional context.
This PR is the last step in graduating the Navigation Drawer component from Beta to Ready.
We have resolved all the outstanding issues in the Navigation Drawer Project here: https://github.com/material-components/material-components-ios/projects/85 and hotlist: 1230549 .
The only outstanding issue is the unit tests ( #5466 , #5465 ) which were approved and are pending due to GitHub issues causing CI not to run.
We are essentially migrating here the NavigationDrawer component from the MaterialComponentsAlpha podspec to the MaterialComponents podspec so it can be used publicly using the normal means of installing our Pod.
This PR is blocked and can land once #5466 and #5465 land.
Closes#5333
### The problem
BottomDrawer previously had no color themer support
### The fix
This change adds a color themer for BottomDrawer. Additionally this adds unit tests and updates the example to use the color themer. The guidelines indicate the content and header should utilize the semantic surface color, so that is what the themer applies to the BottomDrawer.
**Note:** The drawer should be configured with its header and content ViewControllers before applying the theme.
### Related issues
Closes#4910
### Code snippet
#### Swift
```
let bottomDrawerViewController = MDCBottomDrawerViewController()
bottomDrawerViewController.contentViewController = contentViewController
bottomDrawerViewController.headerViewController = headerViewController
MDCBottomDrawerColorThemer.applySemanticColorScheme(colorScheme,
toBottomDrawer: bottomDrawerViewController)
```
#### ObjC
```
MDCBottomDrawerViewController *bottomDrawer = [[MDCBottomDrawerViewController alloc] init];
bottomDrawer.contentViewController = contentViewController
bottomDrawer.headerViewController = headerViewController
[MDCBottomDrawerColorThemer applySemanticColorScheme:self.colorScheme
toBottomDrawer:bottomDrawer];
```
### Context
In working on navigation drawer bugs the navigation drawer presents itself right when you open the example view controller.
### The problem
This makes it hard to do screenshot testing and harder to work on because you have to go back to the table view and then select the example again every time you want to present.
### The fix
Add a button to present the navigation drawer.
Removes the need to copy-paste stanzas from other files anymore as we'll rely on #4478 to generate the correct stanza for us instead.

Adding the navigation drawer component that adds a presentation controller for showing UIViewControllers as a bottom drawer.
History of the component (last CL submitted for it): cl/209765207
Design doc: go/mdc-ios-navigation-drawer
This component will be the first alpha component in this repo, this means that it can still change and will not be included as part of the podspec at first.
