Added tests for the setVertex() method in the Line class.
Finished up the current Vertex class, Including the frustrating addLine() function, and the test class
Made minor adjustments to Line class header and did some work with the test
cases for the classes.
Fixed the bug in the line class that would return the value for the first line's next vertex as being nil.
Fixed resize method. Vertex class should be good to go now.
Merge branch 'master' of https://github.com/shamor/Senior-Design-I

Created header file for DFS.cpp file. Adjusted files to include  dfs.h
instead of *.cpp files.

Conflicts:
	Makefile
	tests/vertexTests.cpp
working on DFS
Have DFS class working and test class written.
working on line detection(incomplete)
unknown but non-problomatic change in vertexSearch.cpp

Pulled from Sam to get code for the line detection method. Made corrections
so that the code for detecting lines would compile.
Did some work on thinning out line families so we can remove some uneccassary lines
Created headder and cpp file for the heapsort algorithm that will help sort
the line_family vector so that it can be processed to remove duplicates.
Also implemented a quicksort algorithm to use until we get heapsort working.
Implemented an algorithm that will thin any lines in the image. Also made
some changes in detectCorners() and lineDetection() methods with their
return types.
lineDetection() method is now usable to create vertices.
Started working on converting a vector to verticies to run through DFS.
