PathFinder followVertex method now accepts vertex instead of vertexIndex as parameter
Modified findAllPaths and changed variable names currend vertex index and now stores current vertex object
Also changed test for path finder followVertex method to pass vertex object not the index
Modified the way boundary vertices are being handled
Instead of null value, pass in a default value of white (255)
Also, keep going through all the vertices including the ones at the right and bottom edge in the findAllVertices method
Changed the test for Vertex now to check if getNeighborPixels that are outside the boundaries have value of 255 instead of null
