Detailed Description

A dummy favicon cache that caches nothing / a fallback solution. The
NullCache is used when more efficient caches such as the
:py:obj:`FaviconCacheSQLite` cannot be used because, for example, the SQLite
library is only available in an old version and does not meet the
requirements.
