incompatibility with jest

[akolu]

There seems to be some kind of incompatibility issue between this package and Jest: all tests which reference a file where face-recognition is imported fail with the following message:

 FAIL  server/__tests__/app.test.js
  ● Test suite failed to run

    Cannot find module '../build/Release/facerec' from 'fr.js'

      at Resolver.resolveModule (node_modules/jest-resolve/build/index.js:221:17)
      at Object.<anonymous> (node_modules/face-recognition/lib/fr.js:6:8)
