docs: Function: paste
  
  Pastes the <cells> into the specified graph restoring
  the relation to <parents>, if possible. If the parents
  are no longer in the graph or invisible then the
  cells are added to the graph's default or into the
  swimlane under the cell's new location if one exists.
  The cells are added to the graph using <mxGraph.importCells>
  and returned.
  
  Parameters:
  
  graph - <mxGraph> to paste the <cells> into.
