/**
 * @description
 * ## Usage
 *
 * The context will be set at ContextAware objects like JsonObject and Collection. By adding a context to the client
 * config the context will be set to all request, responses and other ContextAware objects. Besides that you can always
 * set a new context to every ContextAware object at any time.
 *
 * ```php
 * $context = Context::of();
 * ```
 *
 * For production environments it's advised to set the graceful flag to prevent Exceptions by toString conversions()
 *
 * ```php
 * $context->setGraceful(true);
 * ```

 * ### Languages and Locales
 *
 * For automatic fallback string conversion e.g. with LocalizedString you can set the available languages. The
 * LocalizedString will try to resolve a string in the given order. It's strongly advised to set the locale in
 * the Context as it is used for example by the CurrencyFormatter. If no locale is set, the default locale given
 * by php config will be used.
 *
 * ```php
 * $context->setLanguages(['de', 'en'])->setLocale('de_DE');
 * ```
 *
 * ### CurrencyFormatter
 *
 * The context provides a builtin CurrencyFormatter. The default currency formatter will format a currency with
 * the help of the intl extension and the locale set.
 *
 * Example for custom currency formatter:
 * ```php
 * $currencyFormatter = new CurrencyFormatter();
 * $currencyFormatter->setFormatCallback(function($centAmount, $currency)) {
 *     $amount = $centAmount / 100;
 *     $currency = mb_strtoupper($currency);
 *     $locale = $this->context->getLocale();
 *
 *     $formatter = new \NumberFormatter($locale, \NumberFormatter::CURRENCY);
 *     return $formatter->formatCurrency($amount, $currency);
 * }
 * $context->setCurrencyFormatter($currencyFormatter);
 * ```
