create_itemsInLevel is does not work for segments with multiple attributes

[FredrikKarlssonSpeech]

There are some issues with create_itemsInLevel, and one of them is that if you have a SEGMENT level with multiple attributes, than you cannot add labels to them.

Error in create_itemsInLevel(egg, itemsToCreate = marks) : 
  Found duplicate sample_start values on same level

The documentation could need some looking over too, but duplicate start ids is kind of the point when you are assigning multiple level attributes, so this needs fixing (and clarification with clear examples).
