docs: Makes an array containing the morgan numbers+element symbol of the atoms
  of {@code atomContainer}. This method puts the element symbol before the
  morgan number, useful for finding out how many different rests are
  connected to an atom.
  
  @param atomContainer The atomContainer to analyse.
  @return The morgan numbers value.
