RotAndStack 1.2

The program determines the rotation to apply to each image for an optimal alignment. It optionally saves each aligned image in the same directory with Aligned in the name. Then it merges all the images and it produces several images based on statistical computations:
An image where each pixel is the brightest of all the original images
An image where each pixel is the darkest of all the original images
An image where each pixel is averaged from all the original images
An image where each pixel goes through a histogram filtering algorithm (maximizes the contrast)
