/**
 * \file
 * \brief C++ API: Library for localized formatting of number, currency, and unit ranges.
 *
 * The main entrypoint to the formatting of ranges of numbers, including currencies and other units of measurement.
 * 
 * Usage example:
 * 
 * <pre>
 * NumberRangeFormatter::with()
 * .identityFallback(UNUM_IDENTITY_FALLBACK_APPROXIMATELY_OR_SINGLE_VALUE)
 * .numberFormatterFirst(NumberFormatter::with().adoptUnit(MeasureUnit::createMeter()))
 * .numberFormatterSecond(NumberFormatter::with().adoptUnit(MeasureUnit::createKilometer()))
 * .locale("en-GB")
 * .formatFormattableRange(750, 1.2, status)
 * .toString(status);
 * // => "750 m - 1.2 km"
 * </pre>
 * 
 * Like NumberFormatter, NumberRangeFormatter instances (i.e., LocalizedNumberRangeFormatter
 * and UnlocalizedNumberRangeFormatter) are immutable and thread-safe. This API is based on the
 * fluent design pattern popularized by libraries such as Google's Guava.
