* FormMain.cs, 14.09.2006
*
* 09.08.2006: Initial version
* 17.08.2006: Display unit "samples/s" in generator test
* Use byte[64] for testing Generator.NextBytes method so the test is less time consuming
* 14.09.2006: Adjusted distribution visualization so that the last interval of histograms is displayed correctly
* (Till now the histogram graphs consisted of points representing the minimum bounds of histogram intervals,
* so the last interval wasn't really drawn; therefor graphs now contain an additional point for the
* maximum bound of the last interval which of course has the same y-value as the corresponding minimum bound)
