==Description==
This script matches GameObjects from one hierarchy to the other, and then clones all components, transferring them to the destination.

==Usage==
Place this script in ''Assets/Editor'' and select the option in the tools menu. Specify the source and destination GameObject hierarchies, as well as an additional prefix on the destination objects. GameObjects in the source without a match in the destination will be skipped and a warning printed. '''NOTE:''' Save your scene before running this script. The functions used tend to mess up Unity's internal data structures and make it crash ocasionally.
