[e-lang] templateTermVisitor

[Mark S. Miller]

Hi Dean,

Your templateTermVisitor[*] is very cool, and works fine for the trees
produced by termE`...`. However, is there any reason why it uses "extends"
instead of composition? Would the sub-object ever want to override any of
super's messages?

[*] I'll let Dean provide explanatory context.
