updated class to read json file and write in a txt file(dataset)

Now this class could read from json file and write the desire format
{scr dst distance } and save them as a txt file.
but the key thing is arraylist could only store 15 lines, we have 42 in total , too late today ,going to extend the  space tomorrow with group mates.

1. now the project could find the path bidirectionally. 
2.add the function to caculate the running time for each action to find the
shortest path. 
3.going to use the format {node,edge,distance}, the distance of each edges could
be caculate by Google Distance Matrix API

https://codereview.appspot.com/336160043/diff/40001/TestDijkstraAlgorithm.java
File TestDijkstraAlgorithm.java (right):

https://codereview.appspot.com/336160043/diff/40001/TestDijkstraAlgorithm.jav...
TestDijkstraAlgorithm.java:11: private static List<Edge> edges;
Why are these variables static? Would this make any difference to declare these
variables without the 'static' keyword?

https://codereview.appspot.com/336160043/diff/40001/TestDijkstraAlgorithm.jav...
TestDijkstraAlgorithm.java:23: Vertex location = new Vertex("hop" + i, "hop"
To make it consistent, if a list of Vertex is stored in the variable "nodes",
then a single vertex could be stored in a variable "node"

https://codereview.appspot.com/336160043/diff/40001/TestDijkstraAlgorithm.jav...
TestDijkstraAlgorithm.java:93: private static void addLane(String laneId, int
sourceLocNo, int destLocNo, int duration) {
This function would be better called 'addEdge', right?

https://codereview.appspot.com/336160043/diff/40001/TestDijkstraAlgorithm.jav...
TestDijkstraAlgorithm.java:94: Edge lane = new Edge(laneId,
nodes.get(sourceLocNo), nodes.get(destLocNo), duration);
To make it clear, would be nice to replace "duration" with "propagation_delay"
or something more accurate if there is?

1. add reading class  now the backrend can read from .txt file (our dataset )
and calculate the latency .
2. use java heap to store data .

I thought we had already solve the problem last time.
