How do I get the 'Fracture' panel to appear in the Toolshelf? What must I do to get the "fracture" panel to appear in the 3D View Toolshelf? I have download the "Blender fracture; version --> 2.79a".

I have made a picture of a Youtube video where I can see that they have the "fracture" panel (I have made a orange circle around the 'Fracture' panel):
No, this addon is bundled with the Fracture Modifier Build, it should be inside the "fracture_extra" folder within the zip file which contains the build. ("fracture_helper.py") Alternatively you can separately download it here:

(Helper Addon)

The addon might also be updated separately from the build from time to time.
