/**
* Copy an object tree. Both source and parent may be liberally filled. Source can be either
* MgdSchema or MidCOM db object or GUID of the object and parent can be
*
* - MgdSchema object
* - MidCOM db object
* - predefined target array (@see get_target_properties())
* - ID or GUID of the object
* - left empty to copy as a parentless object
*
* This method is self-aware and will refuse to perform any infinite loops (e.g. to copy
* itself to its descendant, copying itself again and again and again).
*
* Eventually this method will return the first root object that was created, i.e. the root
* of the new tree.
*
* @param mixed $source GUID or MgdSchema object that will be copied
* @param mixed $parent MgdSchema or MidCOM db object, predefined array or ID of the parent object
* @param array $exclude IDs that will be excluded from the copying
* @param boolean $parameters Switch to determine if the parameters should be copied
* @param boolean $metadata Switch to determine if the metadata should be copied (excluding created and published)
* @param boolean $attachments Switch to determine if the attachments should be copied (creates only a new link, doesn't duplicate the content)
* @return mixed False on failure, newly created MgdSchema root object on success
