Eric Nakagawa 4243d682a0 Docs: Basic Components Update
Summary:
This is an improvement to basic components docs.

* I updated the basic components example code to better render components on iOS (added paddingTop).
* I also modified the code to allow reader to easily copy, paste, and then run the code in their project if they followed the 'Getting Started' quick start guide.
* I also added additional copy to clarify suggested usage/guidelines.
Closes https://github.com/facebook/react-native/pull/8292

The most basic component in React Native is the [`Text`](/react-native/docs/text.html#content) component. The `Text` component simply renders text.
This example displays the `string` `"Hello World!"` on the device.
```JavaScript
import React from 'react';
import { AppRegistry, Text } from 'react-native';
const AwesomeProject = () => {
return (
<Text style={{marginTop: 22}}>Hello World!</Text>
);
}
// App registration and rendering
AppRegistry.registerComponent('AwesomeProject', () => AwesomeProject);
```
In this slightly more advanced example we will display the `string` `"Hello World"` retrieved from this.state on the device and stored in the `text` variable. The value of the `text` variable is rendered by using `{text}`.
```JavaScript
import React from 'react';
import { AppRegistry, Text } from 'react-native';
var AwesomeProject = React.createClass({
getInitialState: function() {
return {text: "Hello World"};
},
render: function() {
var text = this.state.text;
return (
<Text style={{marginTop: 22}}>
{text}
</Text>
);
}
});
// App registration and rendering
AppRegistry.registerComponent('AwesomeProject', () => AwesomeProject);
```
