/*******************************************************************************************
* There could have been several approaches to this problem
* 1)Taking this as directed graph.
*
* 2)Making a global time controller which could raise ticks and synchronise all objects
* like traffic lights, driver's action based on every tick.But this approach is more suitable
* in case of simulations when there are several objecs etc.
*
*
* 3)So, I have taken the third approach as per problem scope and to maintain simplicity.
*
* The following assumptions have been made :
* All units are same..like time in minutes, secs or hrs
* Traffic light will assume the next light if the previous light duration is just over.
* i.e during the transition of lights old to new ...new light will be assumed to operate.
*
* Car is in "Start" state and at the start of journey and lights are green
*
* Basic design is :
*
* Route is composed of places which could be stretch or traffic light
* Driver will select driving strategy based on place
* Traffic light will give the waiting time based on elapsed time ..time passed since start of journey.
*
*
*
* Test cases have assumed same time unit..for all entities
* * *******************************************************************************************/
