/**
 * A wrapper for making views respond properly to touches.
 * On press down, the opacity of the wrapped view is decreased, which allows
 * the underlay color to show through, darkening or tinting the view.
 *
 * The underlay comes from wrapping the child in a new View, which can affect
 * layout, and sometimes cause unwanted visual artifacts if not used correctly,
 * for example if the backgroundColor of the wrapped view isn't explicitly set
 * to an opaque color.
 *
 * TouchableHighlight must have one child (not zero or more than one).
 * If you wish to have several child components, wrap them in a View.
 *
 * Example:
 *
 * ```
 * renderButton: function() {
 *   return (
 *     <TouchableHighlight onPress={this._onPressButton}>
 *       <Image
 *         style={styles.button}
 *         source={require('./myButton.png')}
 *       />
 *     </TouchableHighlight>
 *   );
 * },
 * ```

 * import React, { Component } from 'react'
 * import {
 *   AppRegistry,
