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

[Terence Parr]

apparently 10,000 is the magic number of iterations to warm up the compilation. Can you do it 10000 times and *then* run your tests?  Take a look in the benchmark dir actually. you'll see my tools based upon reading cliff click and josh bloch on micro benchmarking.

still, great news :)  once we get over compilation, I wonder how much faster just exec time is.

I tried to only benchmarked the ST code and ignored all the I/O and reflection. The only exception is that in both cases the template is loaded from a file using ST API calls. So it looks like that means ST4 is 47% faster then ST3 according to my meatball benchmarks.
