@DaveOrDead need to look at this.

Currently returns Infinity.

Right now we have to have all constants come before the DOM constant otherwise the createOutputScreen() function can't access any of them, and it does access one of them: NUMBER_BUTTON_TEXT_NODES.zero.display.

So the initialisation of this function should be done better, currently in constants.js:

import createOutputScreen from './createOutputScreen';

export const DOM = {
    root: document.getElementById('calculator'),
    outputScreen: createOutputScreen()
};

They're technically not operators.

1. Number keys map to the number buttons.
2. SHIFT + operator for the operator keys.
3. Copy and paste shortcuts work.
4. ESC = clear.
5. ENTER = '='.

Needed as the value attr value sometimes needs to be different from the text node.

For now the main thing is to add a comma when appropriate.

And if decimal point is pressed first prepend a zero.
