/**
 * @file
 * @brief The VTranslation class help store string for translation.
 *
 * I took idea from this article http://ololoepepe.blogspot.com/2013/08/qt.html.
 * As you know, if wrap string to a function translate, it will be marked for translation. No matter what namespace
 * contains this function. In class Translation used this circumstance.
 * This mean never change name of method translate!!!!!.
 * Instead of using QT_TRANSLATE_NOOP3 macros we can store strings in QMap.
 * Example:
 * create map and fill up its
 * QMap<QString, VTranslation> map;
 * map.insert("head_girth", VTranslation::translate("Measurements", "head_girth", "Around fullest part of Head."));
 * get translated string
 * map.value(measurement).translate();
 *
 * Hint. Define macros translate() for reducing code complexity.
 * #define translate(context, source, disambiguation) QmuTranslation::translate((context), (source), (disambiguation))
 *
 * Don't forget to undef macros later!
