use material ui for smaller repo

[mnlbox]

Hi @alexdevero ,
I think maybe it's better to use some UI library like material-ui then we have a smaller repo and content specially in src/components directory.

@mnlbox the answer is no. This boilerplate is design-agnostic on purpose. It is not supposed to dictate any design or style direction. It provides just the necessary minimum so people can customize it as they want, This includes their own preferred design, style and potential UI library.
