/* NOTES:
- When building for production I get "ModuleConcatenation bailout" messages because I'm not writing ES6 javascript, so at some point it may be worthwhile converting the code to ES6 in order to improve optimisation.

- The 'bail' true and 'optimizationBailout' true settings don't alter the output, whereas I thought the first ModuleConcatenation bailout should halt webpack, and I should get more info on what caused the bailout.
