[stringtemplate-interest] visualizer mockup

[Sam Harwell]

When you call render(), have a RenderOptions enum/flags parameter with a
value that specifies DebugOutput (or VerboseOutput?). In that mode,
things like "Enter Template", "Leave Template", "Write Template Text",
and "Write Object Text" are written in order. The text output is escaped
for parsing this file later.

The entire session can be reconstructed from this linearization, and it
would be *easy* to support this output without cluttering the ST library
or worrying about things like language/platform issues or protocols.

I think we should collect all data like a flight data recorder and then
ship to the GUI.  Unlike AW, i doubt step by step eval is useful.

static data but interactive

Yeah, Gerald pointed out a file of text would be better all at once.
sockets are more complicated. we want multiple targets to be able to use
same gui.
