steel-cent, currency and money values for Rust

Features

• A value type for currencies: Currency
• Two value types for monetary amounts: Money and SmallMoney
• Customizable formatting of money values
• Currency lookup by ISO 4217 alpha (e.g., "USD") or numeric (e.g, 840) codes

TODO

• Money parsing
• Look up currency by country code
• Support omitting zero minor part in FormatSpec
• Accept Into in Money ops (maybe)
• Support for adding custom currencies to lookup table
• Include pseudo-currencies w/o decimal places (not sure how that should work)
• Include historical currencies (maybe)
• Include non-standard (crypto-)currencies (maybe)
• BigMoney backed by BigInt (maybe--Who needs more than 92 quadrillion dollars?)
• Is there a better way to do pre-defined FormatSpecs than public lazy_static vals (w/ confusing struct defs)?

Joda

The design of steel-cent is largely inspired by the excellent Joda Money Java library. It also uses Joda Money's currency data.
