A material checkbox element made with lit-html. It's an wrapper of [mwc-checkbox](https://github.com/material-components/material-components-web-components/tree/master/packages/checkbox) element. Supports all the features of `mwc-checkbox`.
## Why don't we use `mwc-icon-button`? - We created `dw-icon` to have extended icon set, sepecific to the app. But, those icons we can't be used with `mwc-icon-button`. - We found issue with `mwc-icon-button` that it can't be resized easily.
