End Points from 3D Logical Skeleton

A function to calculate end points from 3D image a skeletonized structure

This is a function that takes in a 3D skeletonized logical image of size MxNxP and prodcues a logical image containing location of end points. I was motivated by the lack of a 3D lookup table (LUT) or bwlookup within MATLAB. This function is ideal for deducing endpoints in vasculature or pipes.
This uses the same input as my other file branchpoints3 and can be called by EP = endpoints3(skel), where EP is the logical image output containing all end points and skel is the logical skeletonized 3D image.
