SOLIDWORKS macro to change layer of selected objects in drawing using SOLIDWORKS API

This macro will move all selected objects in the drawing sheet to specified layer using SOLIDWORKS API.

There is no common ::Layer SOLIDWORKS API property to change the layer for any entity, rather this property is added to each interface which supports it (e.g. ISketchSegment::Layer property). This macro checks the type of the entity and calls corresponding SOLIDWORKS API property to change the layer.
