Detailed Description

Achieves a list of LayoutElementRecord from the Clipboard. The list should be obtained by the root records of a HierarichalRecordList and thus not contain any descendant of any other contained element.

For the execution, the records and all their descendants are copied while the position (all concerning layout attributes) are shifted SHIFT_FOR_COPY points to the right bottom to give feedback about successful execution.

Note, that copies inserted on the same place would just hide the originals, making it difficult to see any effect.

An undo corresponds to a delete, a redo to an undo-delet. For better reuse a DeleteRecordsCommand is used as member.
