Modified Tests.js to get rid of hardcoding and work for files having variable number of test methods. Now any number of tests can be exported and can also be named anything(As opposed to being 'test' from earlier).
Modified 2Sum_Test.js to demonstrate an example.
(Note, I manually tested and ensured both the test methods inside 2Sum_Test.js were actually being invoked, since we had a bug earlier where we were exporting all functions but only test() was being invoked)
test()was being invoked)
