statistical analysis for calculation timings

[haraldschilly]

The attached script does some statistical analysis and plotting for a series of timings done with timeit. It should help to understand how the performance of an algorithm does work out and also how the underlying framework and hardware behaves under load. It shows a time-series, a histogram and CDF plot. It does reject outlyers based on quantile-margins and starts with a dedicated warmup phase. Additional features are possible. Plotting is done via matplotlib, this should be changed to Sage-specific routines.
