Gray-world white balance algorithm

This algorithm scales the values of pixels based on a gray-world assumption which states that the average of all channels should result in a gray image.

It adds a modification which thresholds pixels based on their saturation value and only uses pixels below the provided threshold in finding average pixel values.

Saturation is calculated using the following for a 3-channel RGB image per pixel I and is in the range [0, 1]:

A threshold of 1 means that all pixels are used to white-balance, while a threshold of 0 means no pixels are used. Lower thresholds are useful in white-balancing saturated images.

Currently supports images of type @ref CV_8UC3 and @ref CV_16UC3.
