Test 2: create a SeamCarver object for a given 736-by-584 picture;
then call findHorizontalSeam(), removeHorizontalSeam(),
findVerticalSeam(), and removeVerticalSeam(), and picture();
once each; count total number of calls to methods in Color
* constructor calls per pixel = 0.0
* getRed() calls per pixel = 0.0
* getGreen() calls per pixel = 0.0
* getBlue() calls per pixel = 0.0
* getRGB() calls per pixel = 0.0
* equal number of calls to getRed(), getGreen(), and getBlue()
==> passed
