Rewrite in TypeScript

[TylorS]

Rewrite in TypeScript so that users can take advantage of typings. Like in cyclic-router

Or at least provide a definition file; which could look something like

declare module 'switch-path' {
  export interface RouteDefinitions {
    [sourcePath: string]: any;
  }

  export interface SwitchPathReturn {
    path: string;
    value: any;
  }

  export default function switchPath(sourcePath: string, routes: RouteDefinitions): SwitchPathReturn;
}
