# 9.1.  Signature Base String
# 
# The Signature Base String is a consistent reproducible concatenation of the request elements
# into a single string. The string is used as an input in hashing or signing algorithms. The 
# HMAC-SHA1 signature method provides both a standard and an example of using the Signature 
# Base String with a signing algorithm to generate signatures. All the request parameters MUST 
# be encoded as described in Parameter Encoding prior to constructing the Signature Base String.
