///////////////////////////////////////////////////////////////////////////////
//
// Primary Verb:
// copy
//
// Synonyms:
// <none>
//
//
// Syntactic Form 1: copy selection to clipboard
// copy
//
// Semantics:
// Copies the current selection to the clipboard. The current selection is
// determined by the current active object. The currently active object is
// a) MCactivefield (the field with insertion point) if not NULL
// b) MCactiveimage (the image being edited) if not NULL
// c) MCselected (the list of currently selected objects)
//
// Result:
// <none>
//
// Exceptions:
// <none>
//
//
// Syntactic Form 2: copy objects to clipboard
// copy { <Chunk> , and }
//
// Semantics:
// Copies the given chunks to the clipboard. The chunks can be:
// - an object
// - a text chunk of a field
// - the clickField
// - the selectedField
// - the mouseControl
// - the focusedObject
// - the selectedImage
//
// An object can only be copied from non-locked stacks.
//
// Result:
// empty if successful
// "can't cut object (stack is password protected)" if one of the objects
// resides on a locked stack.
//
// Exceptions:
// EE_CHUNK_CANTFINDOBJECT if one of the chunks cannot be found
// EE_CHUNK_BADCONTAINER if one of the chunks is not of an allowed type
//
//
// Syntactic Form 3: copy objects to container
// copy { <Chunk> , and } to <Chunk>
//
// Semantics:
// Copies the given object chunks to the target container. Compatibility
// of the source and target is checked - AudioClips, VideoClips and Cards
// can only be copied to a Stack. All other object types can only be
// copied to a Stack, Card or Group.
//
// An object can only be copied from non-locked stacks.
//
// If no exception occurs, the 'it' variable is filled in with the long id
// of the last object copied.
//
// Result:
// empty if successful
// "can't cut object (stack is password protected)" if one of the objects
// resides on a locked stack.
//
// Exceptions:
// EE_COPY_NODEST if the target object could not be found
// EE_COPY_NOOBJ if a source object could not be found
// EE_COPY_BADDEST if a source object is not compatible with the target
// EE_COPY_BADOBJ if the source object is not a type that can be copied
// EE_COPY_BADMIX if the collection of source objects is invalid
//
// Description:
// This class implements the 'copy' command.
//
// It has the following syntactic forms:
