This will allow the owner of a button bar to react to changes in the button bar's intrinsic size.
We need to add this delegate because I'm not aware of an equivalent UIKit mechanism that works with views that aren't using auto layout (the MDCNavigationBar uses manual layout).
In a follow-up change, MDCNavigationBar will implement this delegate and update the layout of its left/right button bars as a result.

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.

Repro case:
Add the following code to a view controller with an App Bar:
```swift
class SomeObject {
@objc func someEvent() {
}
}
let object = SomeObject()
self.navigationItem.rightBarButtonItem =
UIBarButtonItem(title: "Right", style: .done, target: object, action: #selector(SomeObject.someEvent))
```
Tap the button.
Expected behavior: the someEvent method is invoked.
Actual behavior: crash due to unrecognized selector `methodSignatureForSelector:`.
After this change the behavior works as expected, with the caveat being that we are not able to pass the button instance along as a third argument to pure Swift classes. The implication of this is that pure Swift classes will not be able to present popovers from the provided item instance. Supporting this case will require turning the pure Swift class into an Objective-C compatible class.
Closes https://github.com/material-components/material-components-ios/issues/2981
Historically we had given navigation bars different heights on iPads. We no longer intent to make this distinction.
This change also fixes a bug related to this difference in behavior on iPads. The repro case for this bug is:
- Launch MDCDragons on an iPad Pro running 10.3.1.
- Open the App Bar typical use example.
- Scroll the content down somewhat.
Expected behavior: the navigation bar does not change its height or shift.
Actual behavior: the navigation bar shifts slightly as the scroll view is scrolled.
After this change, the navigation bar's height will always default to the same fixed height on all devices. This reflects the fact that Flexible Header's default minimumHeight and maximumHeight values are constant across all devices.
Closes https://github.com/material-components/material-components-ios/issues/4840
Many of our Swift examples are either missing imports or are importing all of
MaterialComponents. Both of these will cause failures during internal builds.
This change further formalizes our pattern of annotating APIs that will be or are deprecated using class categories. Moving an API into such a category has the benefit of being picked up by the API diff toolchain and elevated into our release notes as a result.
As part of our readme generator, components can now opt in to displaying badges in their readme.
The badges are generated from https://shields.io/ and are focused on an individual component. We're currently generating the following badges:
- Open bug count.
This discourages depending on all of a component's extensions and aligns our targets more closely with how we expect them to be imported and depended upon.
This is a breaking change.

ButtonBar, FlexibleHeader, HeaderStackView, and NavigationBar are all implementation details of AppBar. While these components can be used on their own, in practice we expect most typical usage to rely on AppBar. FlexibleHeader is a bit blurry in that there is often value in relying on it solely, but because it is not a true concept in the spec and its behavioral demos largely overlap with AppBar's, it is now a dragons demo.

We do not intend to actively support UIAppearance any further. This change removes any references to supporting UIAppearance from our public documentation.

Made colorScheme and typographyScheme properties in the class interfaces for all our examples.
Moved theming away from example inits and into viewDidLoad
Small update for slider example to allow it to grab the theming properly.

Button frames need to be updated after the font changes because their frames are not dynamically updated in any layoutSubviews pass.
It may be sensible to update layoutSubviews to do the frame calculations in a follow-up change, but this has the potential to be a behaviorally-breaking change so I've filed a follow-up story: https://www.pivotaltracker.com/story/show/156930078
Make inkColor for buttons in MDCButtonBar customizable. Also expose an API on MDCNavigationBar to allow using the custom inkColor in AppBar.
closes#1660
Internal clients have broken layouts when using custom titleViews after this
change. Reverting as a hotfix until a migration path can be developed.
This reverts commit 7172657a7b1cd04839eadc10e9d66e895a71bee7.
* Allow setting a custom height on MDCNavigationBar and MDCButtonBar. Currently, these two components don't respect the height that is used for MDCAppBar, and position the buttons incorrectly when a height other than 56.0f is used.
* Make MDCNavigationBar and MDCButtonBar size dynamically instead of exposing an API.
* Fix whitespace
* Maintain previous functionality by checking size.height > 0 in sizeThatFits: for both MDCNavigationBar and MDCButtonBar.
