  # To use this correctly there are two methods:
  # 1: pass a block which will be yielded to, aftewards logout will be called
  #    automatically.
  # 2: call it in a before(:each) {} block with an
  #    after(:each){logout} or be sure to call logout after the call
  #    to reset tests to a working state
