List abstracts (very barebones) 

After hours of toiling around finnally figured out that we could not access s3 becasue of CORS config was not set. I thought that someone already did this from past discussions. Whatever. But the good news is that this is proof we can connect to our aws resources. I simply called the s3 function in the AwsService. NOTE: this is not in pretty angular form yet. Pretty raw. will put it in controllers and stuff later, when less stressed.
