Context

Before beta.36 it was easy to change checkbox size. After beta.36 I don't know how to change the size of the embedded SVG Icon and there doesn't seem to be any information in the documentation.

Your Environment

| Tech | Version |
|--------------|---------|
| Material-UI |beta.40 |
| React | 16.3 |
| browser | chrome 65 |
| etc | |

It is not clear from the documentation which style needs to be overwritten to control the size of a checkbox using the classes property of the checkbox component.

@rwollgar You have missed our demo in the documentation: https://material-ui-next.com/demos/selection-controls/#checkboxes.

Might be late to the party, needing to change the checkbox size as well, searching around this css worked...

.myCheckBox {
transform : scale(2);
}

Anyone else who might needed this, try it out:)
