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.
- Optionally override onSpawn to run code when the child isolate is spawned
- Override onData to handle data sent by the parent isolate
- Use sendToParent to send data to the parent isolate
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.
