Updated utility program "testMe.js" that allows for simple one-shot scripts to be run using LJM & node

updated asyncTest.js to work with this git repo.  blockingTest.js is
still out of date
run.sh is updated so that:
'./run.sh true 9'  asynchronously runs sequence 9
Trying to find out & create a test for writing all zero's to a labjack
using the rwMany function call.  This doesn't find it but the code
still builds & passes all tests.
