This line is the result of a merge conflict.  Git merge conflicts happen when the same part of the same file is changed by two different people.  It's actually pretty easy to fix.  Git doesn't delete anything (since it doesn't know which one you want).  Instead it actually puts BOTH versions in the file.  It has a format like this

<<<<<<<<<<<<<<< HEAD

(This is the version that YOU wrote)

================

(This is the version the other person wrote)

>>>>>>>>>> Name_of_the_other_person's_repository

You deleted your copy, but didn't delete the notes from git!  (That's all the ============ and >>>>>>>>>> stuff)

I'll delete this for you, but wanted you to know what was going on.
