h2.  Defining regions
 
* An Fqn can define a Node which is the root of the region
* Regions within regions allowed
 
h3.  Configuration
 
* Each region to have a Configuration, which inherits from it's parent region (if region is within a region) or the cache-wide default (copies it)
* Some elements may be dynamic
** If changing on the fly, acquire an exclusive lock on all nodes in the region (and any sub-regions)
** Update interceptors on all nodes in the region accordingly
** Release exclusive locks 
*** Any eviction policy updates in a region will reset eviction queues!
