parse_name('remotes/origin/master/v2') #=> ['origin', 'master/v2']
parse_name('remotes/origin/master') #=> ['origin', 'master']
# remote branches

parse_name('origin/master/v2') #=> [nil, 'origin/master']

Given a full branch name return an Array containing the remote and branch names. 
def parse_name(name)
  # Expect this will always match
  match = name.match(BRANCH_NAME_REGEXP)
  remote = match[:remote_name] ? Git::Remote.new(@base, match[:remote_name]) : nil
  branch_name = match[:branch_name]
  [ remote, branch_name ]
