/**
* @fileoverview A utility to get better currency format pattern.
*
* This module implements a new currency format representation model. It
* provides 3 currency representation forms: global, portable and local. Local
* format is the most popular format people use to represent currency in its
* circulating country without worrying about how it should be distinguished
* from other currencies. Global format is a formal representation in context
* of multiple currencies in same page, it is ISO 4217 currency code. Portable
* format is a compromise between global and local. It looks similar to how
* people would like to see how their currency is being represented in other
* media. While at the same time, it should be distinguishable to world's
* popular currencies (like USD, EUR) and currencies somewhat relevant in the
* area (like CNY in HK, though native currency is HKD). There is no guarantee
* of uniqueness.
