val react : Types.date -> context -> stimulus list -> context * response list

react t ctx stimuli computes a global reaction in ctx at time t given a set of stimuli stimuli, producing an updated context ctx' and a set of responses resps. The (operational) semantics is that of StateCharts. A reaction is viewed as a (finite) sequence of "micro-reactions". Each micro-reaction can generate stimuli which can trigger another micro-reaction (the related stimuli are here called "reentrant". However, a given FSM can only react once during a sequence of micro-reactions (this is implemented by partitionning FSMs into active/inactive subsets during a reaction. A reaction ends when all the micro-reactions have taken place, i.e. when the last one did not produce any further re-entrant stimulus.

val run : Static.t -> context * (Types.date * response list) list

run m runs a simulation of system m, returning the final context and a list of timed responses
