### Example policy
As part of the policy, you will start deciding which top level configuration to use, then which Evictor plugin to use (if you have your own, the Default Evictor if not), followed by deciding the configuration passed to the Evictor Plugin. After that you will enable/disable eviction strategies plugins and configure them properly.
