	PPM (const char *filename)

void	loadFile (const char *filename)
	Load a .ppm file. Throw an exception in case of an error.

void	saveFile (const char *filename)
	Save image data to a .ppm file. Throw an exception in case of an error.

unsigned int	getWidth () const
	Get the width of the loaded image.

unsigned int	getHeight () const
	Get the height of the loaded image.

void	setWidth (unsigned int width)
	Set the width for the loaded image. This must eventually match the number of pixels, if saveFile() gets called.

void	setHeight (unsigned int height)
	Set the height for the loaded image. This must eventually match the number of pixels, if saveFile() gets called.

const std::vector< Color > &	getPixels () const
	Get read-only access to the pixels in the image. To access a pixel at coordinate (row,col), use getPixels()[row * getWidth() + col].

std::vector< Color > &	getPixels ()
	Get write access to the pixels in the image. To access a pixel at coordinate (row,col), use getPixels()[row * getWidth() + col]. This must eventually match the width & height set by setWidth() and setHeight().

const Color &	getPixel (const int row, const int col) const
	Directly access a pixel in the image.

Color &	getPixel (const int row, const int col)
	Directly access a pixel in the image.
