addreactioncallback!(s::SysDef, reactantexpr::AbstractString, rate::Float64, invvolumepower::Int, callback)::SysDef

Like addreaction! but also adds callback. callback is called when the reaction happens with input of MEDYAN.Context and Int the chem_voxel id where the reaction happened.

The callback should handle updating species counts.
