Bare translation of the bits I needed from react-jss/lib/JssProvider just to integrate with bs-material-ui

JssProvider.re

[@bs.module "react-jss/lib/JssProvider"]
external myJssProvider : ReasonReact.reactClass = "default";

let make = (~jss: InsertionPoint.jssObj, ~generateClassName: string, children)=>
  ReasonReact.wrapJsForReason(
    ~reactClass=myJssProvider,
    ~props={ "jss": jss, "generateClassName": generateClassName},
    children,
  );
