/**
* This is a set of APIs that are of general usefulness for user interface
* internationalization.
*
* They're all in various stages of the standardization process through
* ECMA402, so they are exposed to privileged content only but are written
* in the way to allow for easy migration to standard Intl object once
* the appropriate stage of the ECMA402 is achieved.
*
* The exact structure of the code is a little bit complex because of that:
*
* 1) The core is in SpiderMonkey together with other Intl APIs
*
* This allows us to write the code once, stick to the spec language
* of the proposal, reuse our ICU bindings in Spidermonkey and use
* the code to inform us on refining the spec proposal for the given API itself.
*
* 2) The MozIntlHelper API exposes the SpiderMonkey APIs
*
* This helper API allows attaching the new APIs on any regular object.
*
* 3) The MozIntl API provides the access to those APIs
*
* This API exposes the actual functionality and wraps around the MozIntlHelper
* lazily retrieving and setting the accessors.
* On top of that, the API also binds additional functionality like using
* current application locale by default, and fetching OS regional preferences
* for date time format.
