Agents can interact with the local value of a continuum. Reactions specify the terms of those interactions, allowing both constant increase or decrease (injection) and proportional scaling (exponentiation).
|exp||Double||Amount by which to scale the local value of the continuum field. Over many iterations, this leads to exponential growth, hence the name.|
|inj||Double||Constant amount by which to increase local continuum value.|
|layer||String||The name of the continuum layer with which to react.|
