/**
* General purpose implemention of the application Context
* interface for general application use. This class should
* be used in place of the original Context class.
*
* This implementation uses a HashMap (@see java.util.HashMap )
* for data storage.
*
* This context implementation cannot be shared between threads
* without those threads synchronizing access between them, as
* the HashMap is not synchronized, nor are some of the fundamentals
* of AbstractContext. If you need to share a Context between
* threads with simultaneous access for some reason, please create
* your own and extend the interface Context
