##  Rename Component Instances - Tool to quickly rename component instances (not definition names)
##
##  1) Select the Rename Component Instances tool from the plugins menu.  
##  2) double click on a component instance
##  3) Enter the new instance name
##
##   I borrowed heavily from TIGs addvertex+ tool, and from Rick Wilson's repaint script
