11  * Creates a simple cache that holds only one key/value.
12  * This cache type can be useful for storing a fairly static but still database driven list,
13  * such as a list of countries.
14  * Obviously, this cache doesn't require a very complex implementation. If a cache
15  * will only ever have one value, then this will be the most efficient implementation.
