Multiple instances of Sketch component
Is it possible to have several independent sketch elements? It seems only a single Sketch component is being loaded on the screen.

To be more specific - this what I'm trying to do:

**Component1** contains a single **Sketch** component:

```
<View>
     <Sketch
          style={styles.notes}
          ref={sketch => {
            this.sketch = sketch;
          }}
          strokeColor="#999999"
          strokeThickness={2}
     />
</View>
```

Then, I create several **Component1** instances:
```
<View>
     <Component1 />
     <Component1 />
     <Component1 />
</View>
```

I expect to see 3 independent Sketch components in which user can draw different strokes. However, only a single Sketch component actually being loaded.
