title: What is the difference between P4V's Branch, Copy, Integrate/Merge
body: <p>I am using P4v, and when i bring up the context-menu on a folder, i have these options:-
  - Integrate/Merge
  - Copy
  - Branch</p>
  
  <p>Seems to me like they are all doing the same thing.
  Is there any real difference in these commands?</p>
  
  <p>thanks.</p>
