* This class is a placeholder for Avalon Context keys.
*
* In order to decouple James from Phoenix, and to allow James
* to run in any Avalon Framework container it is necessary that
* James not depend on the BlockContext class from Phoenix, but
* rather only on the Context interface. This requires that we
* look up context values directly, using String keys. This
* class stores the String keys that are used by James to
* look up context values.
*
* The lifetime of this class is expected to be limited. At some
* point in the near future the Avalon folks will make a decision
* about how exactly to define, describe, and publish context
* values. At that point we can replace this temporary mechanism
* with the Avalon mechanism. Unfortunately right now that decision
* is still unmade, so we need to use this class as a temporary
* solution.
