* [react-is] Initial typings for package React introduced the react-is for assertions on elements and element types. I took the README and tests and created the matching ts types. * Add TypeScript 2.6 comment this package uses @types/react, and it requires 2.6 or above. * Match strictFunctionTypes config of react * Remove unneeded generics per https://github.com/Microsoft/dtslint/blob/master/docs/no-unnecessary-generics.md React uses this pattern (providing the Props interface via generics) and turned off the linting. We'll use the default lint options and `any` props. * Use ReactType instead of an explicit union * Cleanup unused imports
