Added *stones small descriptions (what they aim to measure).

Finally it has an its own page. I have done it just to
publish same of the results.
This program is written to face a sort of funny war with my friends:
AMD Athlons vs Pentiums 4.
I have looked around the net but I haven't seen anything that fits to
my purpose.
I want to sample the raw CPU processing power.
So I have ressurrected the Dhrystones and Whetstones benchmarks from
old sources that I found in the net. They sample exactly CPU
processing power without being affected by RAM, video cards, OSs...
I have made only few changes:
- the samples are expressed in KiloXStones (i.e. stones/1000).
IMHO Drystones & Whetstone (see the Results section for
their description) are still covering most of the daily CPU
usage.
- I have engineered these tests to last x msecs. I repeat many 1000ms
tests many times (alternating the sampling Dhry.., Whet..., Dhry...).
This should be a problem for any prediction algorithm.
- I have compiled it using Borland C++ Builder 6.sp2 with Pentium
instruction set (i.e. without Intel or AMD specific optimizations).
Here same of the collected results.
Drystones are representing the linear data processing (integral
math, memory copy, strings, ...).
Whetstones are representing the floating point math processing
(used by 3D engines, calc. programs, ...).
