No Camel dependencies! (other than for a log4j-camel module)

I linked that Camel thing because that's what I thought was being hinted
at. Camel invented their own expression language called simple that is like
EL minus the functions. Something like that might be a choice to implement
if it were useful, but I can't really think of how it would be useful in a
way that specifying a typed default value wouldn't be.
