This didn't really work too well, the file just gets too big. Maybe if we could improve the generated json in cereal, but that's too much effort for now.

Otherwise, it looked like JSONlab will not write the output file, probably because it's >1GB. See GitHub issue #29.

* The inner mouth corners are not mapped since I think they don't realy exist in the 3D model.
* Some points are not defined on the reference and only present in the 3448 model and above.
* A few of the selected 3D vertices could be improved a bit, I have some notes on it, if someone is interested, contact me.

The file contains blendshapes for these 6 facial expressions:
angry, disgust, fear, happy, sad, surprised.

These are reduced in number of vertices to match the low-resolution (3448 vertices) shape model.
They should be considered beta-quality.

- Updated ibug2did.txt with a description of the contour indices
- Added a file describing the left and right model contours (the face outline) on the reference model
- Caveat: The implementation is a bit poorly documented for now
