The Evolver can transform into a designated GameObject (the buildItem that was selected). The process of transformation is purely visual, but once the build time of the selected buildItem is complete, the Evolver immediately transforms into it.
Currently all Evolvers are hardcoded to use a model file called 8472_cocoon.sod to display their cocoon animation as they transform. Evolvers are hardcoded to play a file called cocoon.wav when the Evolver completes / stops transformation.
Evolved units inherit the parent's previously defined possibleCraftName.
Note that the AI will not use Evolvers in combat and thus the classlabel provides a way to ensure that certain types of ships do not enter the battlefield.
classLabel = "evolver"
Does not have any special ODF commands.
