Monkeys, Lemurs, and Baboons: What are they?

From reSIProcate

The repro design has three different feature chains

• Features that handle requests; may send responses or add a target to the Request Context. These are “monkeys”
• Features that can modify requests that are generated post target selection, “baboons”
• Features that modify responses and the final response which is sent back to the server transaction, “lemurs”
