Add functions to merge two stacks, add an image to a stack, remove an image from a stack, ...

@lpatiny , do you think this kind of function would be useful? If yes, could you please give an example of application?

We outlined the following application for stacks: the goal is to find the rois that blink in a tiff stack. We have to load the tiff, find the rois and check their intensity in each image.

Steps:

• load tiff stack
• compute max image
• find Rois
• compute mean intensity for each roi for each image of stack
• return array of objects with ROI data, means and medians for each image
