[benchmarks] GSoC Report

Hi I'll make a short report here of what I've done and what is next. The recent days I've been improving the main benchmark script and added the PEAR package console_getargs instead of the earlier implementation. The benchmark is working but needs additional content, more functionality and "better" results. With better results, I mean to embed valgrind (cachegrind) to the benchmark and include relevant results in the output. The next thing that needs to be done is to add some more tests and I'm thinking of adding the Whirl and j4p5 as the next tests. I believe they will fit well. This is followed by the valgrind implementation. Thanks!
