new SurrogateSideEffect()
This class is inherited by all side effects which changes the look of any existing elements in the visualization.
For example, if a side effect wants to change the color of bar plots, then it is a surrogate side effect.
To use this,
```
const SurrogateSideEffect = muze.SideEffects.standards.SurrogateSideEffect;
class BarColorChanger extends SurrogateSideEffect {
static formalName () {
return 'colorChanger';
}
// Implement the logic of applying the style here.
apply () {
}
}
```
