Compile/run:
     - Compile using
            make MetroSim
     - run executable with
            ./MetroSim stationsFile passFile [commands]


Program Purpose:
     Create Metro Simulation that move trains and deal with passengers 
     going on/off the train.

Acknowledgements:

Files: 

main.cpp:
     Create a MetroSim class variable with the data provided by the user 
     and call the runTrain method to run the game.

MetroSim.cpp:
     Implementation of MetroSim class.  Main functionality of running the 
     Metro Simulation: move trains and deal with passengers 
     going on/off the train.

MetroSim.h:
     Interface of MetroSim class.

stations.txt:
     an example file containing a list of stations.

test_commands.txt:
     sample list of commands that you could give to the simulator

the_metroSim:
     reference implementation for students to see how 


Note:  the program should handle all cases.

Data Structures:

     The program uses vector and list to create two arrays of queue to handle 
     the stations and train. New passengers will be placed in the station's 
     queue corresponding to their arrival and the train's index corresponding 
     to their depqrture.


Testing:

Here describe the following: process of testing (unit tests), mention
of bugs you encountered while testing, mention of testing on inputs of
different sizes and edge cases, good description of base cases you
considered while testing. Demonstrate a methodical approach to
testing.  This section of your REAMDE should be very thorough for
assignments.

Note: This assignment comes partially implemented, but student must also
create the driver and add class functionality.

Part that you found most difficult:

     It was challenginf at the beginning to understand the flow and concept
     of the program as well as the input stream and output stream. But
     everything got better after I have my program design.
