#dijkstra's algorithm for computing geodesics.

• uses C++11 and google test for some testing.
• REquirements - CImg.h - needed for images based testing [refer to CMakeLists.txt inside main].
• How to use - ./main/fit [image-path] Click on some points to select seeds - as many seeds as valid inputs. Close the image window and click spacebar to see segmentation id.
• Currently, for images - L2 norm between pixel values is the geodesic distance.
• For other graphs, please see test/ folder.
