Small GUI to visualize a 3D frame stack

GUI to visualize a 3D frame stack with fixed color range. Allows quick comparison of 2D matrices and tracking of changes in 3 dimensional data sets.Can apply a 2D gaussian- or a box-filter to smooth an image and save selected frames back to the base workspace.
Input: A 3-D matrix of arrangement X,Y,Frames to scroll through.
If input is a 4-D matrix,'Showstack' will average over the last dimension.
GUI inputs:
Colorrange is given by min and max color.
The slider at the figure bottom is used to scroll through frames in the stack. Filter length determines the size of a filter that can be applied to the image. The filter type is either a gaussian or a box filter and can be chosen with the drop-out menu at the bottom left. If chosen filter is gaussian, the sigma of the kernel is determined by 'Filter sigma'.
Smoothed frames can be saved to base workspace using the 'Save to workspace' button in the top left button. Depending on filter length, the smoothed frame will be slightly smaller as the original frame because the code only uses the 'valid' part of the frame without zero-padded edges.
