Modified the Makefile slightly so that the 'make test' command will
compile all the code meant for testing purposes.
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.
