added printer for plat_forms style reports

Hi

I added a printer that prints a report suitable for our plat_forms comparison. It basically just prints the subroutine table with the columns:

Name, File location, Time, Avg. Time, Own Time, Invocation Count, Level

I also added a test for this printer, that checks for a toy program if all methods are printed in a CSV parseable format by Regex matching. I extended the tests scripts for this type of verification.

I would be glad if this got accepted into NYTProf a great profiler :-)
