[stringtemplate-interest] ST4 faster then ST3, some quick numbers

[Collin Fagan]

Warming up for 10,000 iterations before executing 1000 operations yields the
following results.

Total ST3 - Time:40.993
Total ST4 - Time:15.497

So this indicates a 62% increase in speed. 62 is close enough to 47 that I
don't think warming up makes much difference, but here it is.

For me and the way I use ST I'm comfortable saying ST4 is about twice as
fast as ST3 and I'm darn happy about that.
