/**
 * Class Civi
 *
 * The "Civi" class provides a facade for accessing major subsystems,
 * such as the service-container and settings manager. It serves as a
 * bridge which allows procedural code to access important objects.
 *
 * General principles:
 *  - Each function provides access to a major subsystem.
 *  - Each function performs a simple lookup.
 *  - Each function returns an interface.
 *  - Whenever possible, interfaces should be well-known (e.g. based
 *    on a standard or well-regarded provider).

   * Retrieve a named cache instance.

   *   The name of the cache. The 'default' cache is biased toward
   *   high-performance caches (eg memcache/redis/apc) when
   *   available and falls back to single-request (static) caching.
   *   Ex: 'short' or 'default' is useful for high-speed, short-lived cache data.
   *       This is appropriate if you believe that latency (millisecond-level
   *       read time) is the main factor. For example: caching data from
   *       a couple SQL queries.
   *   Ex: 'long' can be useful for longer-lived cache data. It's appropriate if
   *       you believe that longevity (e.g. surviving for several hours or a day)
   *       is more important than  millisecond-level access time. For example:
   *       caching the result of a simple metadata-query.
   *
   * @return CRM_Utils_Cache_Interface
   *   NOTE: Beginning in CiviCRM v5.4, the cache instance complies with
   *   PSR-16 (\Psr\SimpleCache\CacheInterface).
