     ck.get_value() attempts to look up the value for that key in the

     If it doesn't find one, it then tries each of the execution
contexts in the currently active dynamic context.
     If it *still* doesn't find one, then it will set the default value
in the outermost execution context and then return that value.

For what it's worth, I find the term DynamicContext much easier to understand 
with relation to these concepts.
