/**
* Number formatter class - locale-dependent number formatting/parsing.
*
* This class represents the ICU number formatting functionality. It allows to display
* number according to the localized format or given pattern or set of rules, and to
* parse strings into numbers according to the above patterns.
*
* Example:
* <code>
* $value = 1234567;
* $formatter = new NumberFormatter("de_DE", NumberFormatter::DECIMAL);
* echo $formatter->format($value);
* </code>
*
* @see http://www.icu-project.org/apiref/icu4c/unum_8h.html
* @see http://www.icu-project.org/apiref/icu4c/classNumberFormat.html
*
* The class would also contain all the constants listed in the following enums:
* UNumberFormatStyle, UNumberFormatRoundingMode, UNumberFormatPadPosition,
* UNumberFormatAttribute, UNumberFormatTextAttribute, UNumberFormatSymbol.
