count Transitions Until
Simulates the chain forward starting from the startState until the desired state desiredState is reached for the first time and returns the number of transitions required to reach the desired state for the first time.
The desired state may be unreachable from the starting state. The transition limit transitionLimit represents the maximum number of transitions allowed before returning. By default, this is 10000. The transition count will be Int.MAX_VALUE in this case, essentially infinity.
Return
the returned value represents one observation of the first passage time from the starting state to the desired state.
