* Enable unit testing for module Network
Adds mocks for certain components, in order to let module `Network` be run in unit tests.
Changes:
- Create a mock object for `hammer.js` when running browserless. The inspiration is taken from [here](https://github.com/uber/deck.gl/pull/658)
- Create a mock function for `window.requestAnimationFrame()` when running browserless in `network/modules/CanvasRenderer.js`
- Added unit test for `Network` to show that unit testing for it now works
- Fixed naming of container in `test/Graph3d.test.js`
Since `hammer.js` is also used in other modules, this fix is potentially an enabler for full-module unit tests for those as well.
