0.1.12

Provide a workaround for a well known issue with OpenCV's imread. After a double-check, if not possible to read a given image, returns {saliency: null}. Fails gracefully.

0.1.9

• Add confidence level based on normalized inverse entropy of saliency map's histogram
• Clean up resultant JSON while keeping some keys for compatibility with old versions (will be removed in a near future)
• Standardize bbox/points as objects
• Better README explaining about NoFlo component and authors
