IsolateChild<S, R> class
abstract
A child isolate that is spawned by another isolate.
A subclass of this should override id to uniquely identify itself among other children. Override onData to handle data sent by the parent isolate, and call send to send data back to the parent. Override run to run code when the child isolate is spawned.
The type arguments S and R represent the types of data that will be Sent and Received,
from the child isolate's perspective. That is, if the parent sends integers and expects Strings,
then S on the child should be String and R should be int -- the opposite of the parent.
