 * `require.import` - An array of modules to be loaded into NodeVM on start.
 * `require.resolve` - An additional lookup function in case a module wasn't found in one of the traditional node lookup paths.

 * `wrapper` - `commonjs` (default) to wrap script into CommonJS wrapper, `none` to retrieve value returned by the script.
 * `argv` - Array to be passed to `process.argv`.
