rsubhak 0.2.0

Recursively traverse a hash or array *ha* (potentially of other nested hashes and/or arrays), doing manipulations. Two methods are available: rsubhak (do substitutions to hash values) and rstrip (strip whitespace from params hash).. Though the initial intent of the rsubhak method was to sanitize the params hash as far as removing currency symbols and/or commas from attributes such as price and quantity, there is a better approach: see the note on the homepage.
