title: What does 'track' mean when creating a new branch in git?
body: <p>I'm using Aptana and Git.  When I go to create a new branch, the following dialog box shows up.</p>

  <p>I was wondering what that 'track' checkbox does, and when it's most appropriate to check it.</p>
  
  <p>I understand the concept of tracking in git, but mostly with files.  I don't seem to understand how it applies to new branches being created?</p>
