 *
 * Handle resizing enclosed View and scrolling to input
 * Usage:
 *    <KeyboardHandler ref='kh' offset={50} >
 *      <View>
 *        ...
 *        <TextInput ref='username'
 *          onFocus={()=>this.refs.kh.inputFocused(this,'username')}/>
 *        ...
 *      </View>
 *    </KeyboardHandler>
 *
 *  offset is optional and defaults to 34
 *  Any other specified props will be passed on to ScrollView

very good 👍
is there a way to merge or I can just update my fork to be in synch with yours ?
