Normalize theme name ? MUI Mui

Is it possible to normalize MUI prefix name for theme :

I can see that there is different upper/lower case way to write css theme
```js
MuiFormLabel: {
root: {
fontWeight: 'lighter',
fontSize: '0.9rem'
}
},
MuiTableCell: {
root: {
padding: '3px 56px 2px 24px'
},
body: {
fontSize: '0.720rem'
}
},
MuiTableRow: {
footer: {
height: 40
}
},
MuiTablePagination: {
toolbar : {
height: 40,
minHeight: 40
}
},
MUIDataTableBodyCell: {
}
```

I think the right way is to used lower case if you want to be "Material UI" compliant
