[JEXL] Adding myself to JEXL component
JEXL developers -
Any objections to me adding myself to the JEXL component?
I will be starting small -- fixing typos and broken/obsolete links and
republishing the website etc. Over time, I'm looking at adding to the
JexlContexts and JexlExprResolvers. For example, some ideas include:
* A "TreeJexlContext", which is backed by a tree of contexts, where
one may point to a current context node and variable resolution
bubbles up to the root until the variable is found (or fails at root).
* A "ScopedJexlContext", to support multiple scopes/contexts,
allowing differentiation of the type context1.foo and context2.foo
* An "ImplicitObjectsJexlContext", where contexts may be populated
with implicit objects for a particular environment that aren't lost on
JexlContext#setVars(Map) -- potentially handled by having a decorated
JexlExprResolver instead.
As a sidebar, Commons SCXML now supports using JEXL expressions in
SCXML documents [1]. I have use cases similar to the suggestions above
and some other usecases may potentially pop up as I think some more
about this.

Cool. I'll give this thread the rest of the week before moving forward.
