DFS Classes
Made an error on last commit of DFS
fixing last mistake
Changes to DFS. Waiting for vertex class to be complete before more progress can be made
Implemented a Line class to store information on how a line should be
drawn. Implemented more methods for the Vertex class. I started
writing test code for both classes; however, niether is complete. The
program can now be given an image and detects corners using Harris
edge detection.
Merge remote-tracking branch 'josh_repo/master'
Few minor changes to DFS
