[Request] Add mdc-layout-grid to angular_components/css

[BKBuEGmbH]

The layout grid is used for the responive design pattern. As this uses only css, it would be nice to include this like the other mdc-web components like elevation and theme.

It should be nice to provide all the components that are not yet integrated. So we could use them as css/scss I don't how your are doing, but for instance, I have to include the cdn in my index.html

  <link rel="stylesheet" href="https://unpkg.com/material-components-web@latest/dist/material-components-web.min.css">
  <link rel="stylesheet" href="styles.css">
  <script src="https://unpkg.com/material-components-web@latest/dist/material-components-web.min.js"></script>

Not really convenient ..... If someone has a better idea ....
