DESCRIPTION:
These samples demonstrate common scenarios like instantiating a client,
creating a queue, and sending and receiving messages.
USAGE:
python queue_samples_hello_world.py
Set the environment variables with your own values before running the sample:
1) STORAGE_CONNECTION_STRING - the connection string to your storage account
