setMaterial(Material): set the override material of the entire linked object

setMaterial([Material,...]): set the materials for the elements of the link

setMaterial({Int:Material,...}): set the material for the elements of the
                                 link array/group by index. 

If material is None, then the material is unset. If the material of an element
is unset, it defaults to the override material of the linked object, if there
is one

type=1:  override visibility
type=2:  no override
type=-1: sub-object link with override visibility
type=-2: sub-object link with override transformation and visibility

sublink: auto delegate to the sub-object references in the link, if there is
         one and only one.

setChildren([obj...],vis=[],type=0)
Group a list of children objects. Note, this mode of operation is incompatible 
with link array. Calling this function will deactivate link array. And calling
setSize() will reset all linked children.

vis: initial visibility status of the children

type: children linking type, 
   0: override transformation and visibility, 
   1: override visibility, 
   2: override none.

setLink(object): Set the link

setLink(object, subname): Set the link with a sub-object reference

setLink(object, [subname,...]): Set the link with a list of sub object references

object: The linked document object or its view object

subname: a string or tuple/list of strings sub-name references to sub object
         or sub elements (e.g. Face1, Edge2) belonging to the linked object.
         The sub-name must end with a '.' if it is referencing an sub-object,
         or else it is considered a sub-element reference.
