Remove Doubles takes a list on Verts and a list of Faces and
removes the doubles, much like Blender does in edit mode.
It doesn’t have the range function but it will round the corrdinates
and remove verts that are very close togther. The function
is useful because you can perform a “Remove Doubles” with out
having to enter Edit Mode. Having to enter edit mode has the
disadvantage of not being able to interactively change the properties.
