Web Service to query for trains in a lineup based on a lineup id

Steps to use the web service:

if no changes made to web service then skip this step

2) publish the web service (aka make it available at the declared URL): "java -cp ../ trainlineup.TrainLineupPublisher"

this executes the web service publisher thru java

3) run the web service client (in a different shell): "node TrainLineupClient.js"
