Using node-pre-gyp to precompile binaries for multiple platforms seems interesting, avoiding waiting times on CI and making building on multiplatforms much easier.

Now we have the following as result:

saliency:
  bounding_rect: <array of arrays as points> box around biggest salient region
  polygon: <array of arrays as points> approximate polygon around biggest salient region
  center: <array as point> center of biggest salient region
  radius: <number> radius of the approx enclosing circle around biggest salient region

We should have the following, preserving the original fields for a while:

saliency:
  bbox: <array of objects> box around all regions
  confidence: <number> inverse/normalized entropy of saliency map histogram
  regions: <array of objects> [ 
    bbox: <array of objects> box around salient region
    polygon: <array of objects> polygon around salient region
    center: <object> center point of salient region
    radius: <number> radius of the approx enclosing circle around salient region
  ]

In this way, we should remove saliency.bounding_rect, saliency.polygon, saliency.center and saliency.radius because a saliency is composed by many regions. The only information regarding all those regions is the saliency.bbox that encloses them. If one wants to draw or use polygon of the saliency, it should iterate over all saliency.regions's bboxes.

We also should have a standard object to bboxes ({x: ?, y: ?, width: ?, height: ?}) and points ({x: ?, y: ?}).
