completed by: rspencer
mentors: Alarantalara, mattsc, Nils Kneuper
Convert the last of the three existing Lua AIs in 'Guardians' (return guardian, stationed guardian or coward) to a Micro AI and document it on the Wesnoth wiki. This should be done as a parametrization of the existing guardian Micro AI, rather than by creating a separate Micro AI.
This task requires tasks Micro AI 'Guardian' Step 1 and Step 2 to be completed first.
