std.benchmark ready for review. Manager sought after

[Denis Shelomovskij]

Very good but minimum isn't a best guess. Personally I (and there will 
be a lot of such maniacs I suppose) will think that this (minimum) time 
can be significantly smaller than average time.

So a parameter (probably with a default value) should be added. 
Something like enum of flags telling what we want to know. At least 
these looks usable: minTime, <some mean time>, maxTime, 
standardDeviation, graph (yes, good old ASCII art).

Yes, graph is needed.
