-- Finally adding code to detect multiple objects

 -- The code is as follows
 -- Take the response column from the matched destination indices keypoints
 -- Take the response coulmn from the overall destination keypoints
 -- Take unique of response array of matched
 -- sort the unique response
 -- compare and return indices where the match occurs for matched dest index to the overall image keypoints
 -- voila! you have the list of indices in the overall that match the given keypoint, the number of indices returned gives an approximat enumber of components that are in the image and also extracting the coordinates of these indices will give us the set of points that make up each object.
