/**
* Container that allows to flip left and right between child views. Each
* child view of the `PagerView` will be treated as a separate page
* and will be stretched to fill the `PagerView`.
*
* It is important all children are `<View>`s and not composite components.
* You can set style properties like `padding` or `backgroundColor` for each
* child. It is also important that each child have a `key` prop.
*
* Example:
*
* ```
* render: function() {
* return (
* <PagerView
* style={styles.PagerView}
* initialPage={0}>
* <View style={styles.pageStyle} key="1">
* <Text>First page</Text>
* </View>
* <View style={styles.pageStyle} key="2">
* <Text>Second page</Text>
* </View>
* </PagerView>
* );
* }
*
* ...
*
* var styles = {
* ...
* PagerView: {
* flex: 1
* },
* pageStyle: {
* alignItems: 'center',
* padding: 20,
* }
* }
* ```
