* i18n PR2 — phone helpers.

|
*
|

|
|
* Validates:
|
||
|
|
* 1. parsePhone yields E.164 + country + display formats
|
||
|
|
* 2. parsePhone returns the empty record for unparseable input
|
||
|
|
* 3. AsYouType formats digits in the country's national style
|
||
|
|
* 4. isValidE164 accepts only E.164 form
|
||
|
|
* 5. callingCodeFor returns the dial prefix
|
||
|
|
* 6. International-format paste detects country
