// Flood
// Floods a mask from a given set of image to determine the contiguous regions
//  1. Check that the (x,y) is within the picture
//  2. Check if the (x,y) coordinate in the mask is unused
//  3. Check if the (x,y) coordinate in the image is non-background
//  4. Check if the (x,y) coordinate in the image is the same color as the fill color
//  5. If all hold, set the label for the pixel, and check each neighbor
//     Otherwise, stop flooding
