rsubhak 0.1.2

Rsubhak can be used to sanitize a params hash. For instance, remove currency symbols and/or commas from decimal fields (e.g. price, cost, quantity), thereby converting '$1,500.00' to '1500.00'. But really, it's quite generic: Recursively traverse a hash or array (ha), searching for all occurrences of hash key (k), and substituting (within their values) all occurrences of pattern (p) for replacement (r).
