// cos_Image_Analyzer finds all the meaningful differences of two COS Images
// (binary, package, commit, and release notes differences)
//
// Input:  (string) rootImg1 - The path for COS image1
//		   (string) rootImg2 - The path for COS image2
//		   (int) inputFlag - 0-Local filesystem path to root directory,
//		   1-COS cloud names, 2-GCS object names
//
// Output: (stdout) terminal ouput - All differences printed to the terminal
