Hector Ramos b1ecb84c97 Standardize on using AwesomeProject for AppRegistry calls. 
Summary:
We've noticed that many newcomers paste sample code straight into a project created using `react-native init AwesomeProject`, but the sample code assumes the user is creating a new project for each example. This PR makes it so that these samples can be pasted into the same project from the Getting Started.
Closes https://github.com/facebook/react-native/pull/14264

The ScrollView is a generic scrolling container that can host multiple components and views. The scrollable items need not be homogenous, and you can scroll both vertically and horizontally (by setting the horizontal property).

This example creates a vertical ScrollView with both images and text mixed together.

import React, { Component } from 'react';
import { AppRegistry, ScrollView, Image, Text } from 'react-native';

export default class IScrolledDownAndWhatHappenedNextShockedMe extends Component {
  render() {
      return (
        <ScrollView>
          <Text style={{fontSize:96}}>Scroll me plz</Text>
          <Image source={require('./img/favicon.png')} />
          <Image source={require('./img/favicon.png')} />
          <Image source={require('./img/favicon.png')} />
          <Image source={require('./img/favicon.png')} />
          <Image source={require('./img/favicon.png')} />
          <Text style={{fontSize:96}}>If you like</Text>
          <Image source={require('./img/favicon.png')} />
          <Image source={require('./img/favicon.png')} />
          <Image source={require('./img/favicon.png')} />
          <Image source={require('./img/favicon.png')} />
          <Image source={require('./img/favicon.png')} />
          <Text style={{fontSize:96}}>Scrolling down</Text>
          <Image source={require('./img/favicon.png')} />
          <Image source={require('./img/favicon.png')} />
          <Image source={require('./img/favicon.png')} />
          <Image source={require('./img/favicon.png')} />
          <Image source={require('./img/favicon.png')} />
          <Text style={{fontSize:96}}>What's the best</Text>
          <Image source={require('./img/favicon.png')} />
          <Image source={require('./img/favicon.png')} />
          <Image source={require('./img/favicon.png')} />
          <Image source={require('./img/favicon.png')} />
          <Image source={require('./img/favicon.png')} />
          <Text style={{fontSize:96}}>Framework around?</Text>
          <Image source={require('./img/favicon.png')} />
          <Image source={require('./img/favicon.png')} />
          <Image source={require('./img/favicon.png')} />
          <Image source={require('./img/favicon.png')} />
          <Image source={require('./img/favicon.png')} />
          <Text style={{fontSize:80}}>React Native</Text>
        </ScrollView>
    );
  }
}

// skip these lines if using Create React Native App
AppRegistry.registerComponent(
  'AwesomeProject',
  () => IScrolledDownAndWhatHappenedNextShockedMe);

ScrollView works best to present a small amount of things of a limited size. All the elements and views of a ScrollView are rendered, even if they are not currently shown on the screen. If you have a long list of more items that can fit on the screen, you should use a ListView instead. So let's learn about the ListView next.
