## Detailed Description

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:

    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"

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.
