Summary:
Hi! I would like to contribute to React Native, and I am just starting out. I forked the repo and found that it has quite a lot of ESLint warnings – many of which were automatically fixable. This PR is simply the result of running `yarn lint --fix` from the root folder.
Most changes are removing trailing spaces from comments.
Haven't really done any manual testing, since I haven't done any code changes manually. `yarn test` runs fine, `yarn flow` runs fine, `yarn prettier` is satisfied.

Summary:
Now that the Component and API docs are no longer auto-generated, we need to consolidate on a new format for our jsdoc comments. Any help from the community will be appreciated.
In this initial pull request, we'll be tackling the following docs:
- `AccessibilityInfo`, an API doc.
- `ActivityIndicator`, a Component doc.
- `View`, a Component doc.
This top comment will serve as a style guide, and when in doubt, please refer to the individual commits in this PR.
Each commit should update a single component or API, along with any relevant markdown files.
- Documentation in the JavaScript source files should be succinct. Any verbosity should be moved over to the markdown docs in the website...
- ...by adding a link to the relevant method/prop on the website to every comment block.
- Avoid markdown style links in JavaScript source files, opt for plain old URIs.
Let code document itself:
- If a method is Flow typed, the comment block does not need to repeat this information.
- If a param can be one of several values, and the type definition is easily determined from the code, the values should not be repeated in the comment block. Again, move this to the markdown doc if not present already.

Summary:
This change introduces some APIs that are useful for making announcements through the screen reader on iOS:
- `announceForAccessibility`: The screen reader announces the string that is passed in.
- `announcementFinished`: An event that fires when the screen reader has finished making an announcement.
You can already solve similar problems with RN Android using the `accessibilityLiveRegion` prop. Live regions are a different feature but they can be used to solve the same problem. This commit does not attempt to add live region support in RN iOS because Apple did not build live region support into iOS.
Verified that `announceForAccessibility` causes VoiceOver to announce the string when VoiceOver is enabled. Verified that `announcementFinished` fires with the appropriate data in the event object. Additionally, my team has been using this change in our app.

Summary:
This change introduces an API, `setAccessibilityFocus`, which moves the screen reader's focus to the passed in element. This causes VoiceOver to announce the element and draw a focus rectangle around it.
Similar functionality is already available in RN Android through the `sendAccessibilityEvent` method. Here's an example of what exists today in RN Android:
```
RCTUIManager.sendAccessibilityEvent(
node,
8 /* TYPE_VIEW_FOCUSED */);
```
Called `setAccessibilityFocus` on a couple of elements to verify that focus does indeed move when VoiceOver is enabled. Additionally, my team is using this change in our app.

Summary:
This PR is based on files ericvicenti gave me. Specifically, he gave me:
- AccessibilityInfo.android.js
- AccessibilityInfo.ios.js
- AccessibilityInfoModule.java
Before this change, only a native iOS implementation of AccessibilityInfo existed. This change includes:
- A native Android implementation of AccessibilityInfo.
- JavaScript wrappers for the AccessibilityInfo module for both iOS and Android.
- UIExplorer changes to illustrate how to use AccessibilityInfo on iOS and Android.
- Documentation for the AccessibilityInfo APIs.
**Test plan (required)**
Tested the UIExplorer AccessibilityInfo example on iOS and Android with the screen reader both enabled and disabled.
