"RVK1 to RVK2" copies deform data (except surface subdivision) of the active
object to the RVK (relative vertex key) of the other selected object.

Usage:

Select the object that will receive the rvk info, then select the deformed
object, enter Edit Mode and run this script from the "Mesh->Scripts" menu of
the 3d View.  If the active object has subsurf turned on and nonzero subdiv
level, the script will ask if it should change that.  Before copying data to
the rvk it will also ask whether it should replace or add a new vertex group.

#  changelog : 
#        - a test on mesh parity between getraw and getrawfromobject  
#          when there is active subsurf division. 
#        - can copy, or not, vertex groups from the original mesh.
