# ==== Notes
# options parameter must include values for :aws_access_key_id and

# ==== Examples
# sdb = SimpleDB.new(
# :aws_access_key_id => your_aws_access_key_id,
# :aws_secret_access_key => your_aws_secret_access_key
# )
#
# ==== Parameters
# * options<~Hash> - config arguments for connection. Defaults to {}.
#
# ==== Returns
# * EC2 object with connection to aws.
