Confusing Error Message if the target server is not running

[trasa]

If you run putter vs. your node project (or anything really) and the project isn't running, the error returned is not very clear as to why things failed.

$  node putter run ../digipen/CS261/Labs/3_CS261_MongoLab_Materials/CS261_MongoLab_Postman.json

Instead, try and catch that and return something useful like "are you sure this is running?"
