Re: Updates to NUnit 2.5

Hi All,

Latest checkins include new version numbering scheme for
NUnit and generic parameterized test methods.

The NUnit 2.5 Alphas were both numbered 2.5.0.0, which could
be confusing. From now the release builds will carry a build
number in the fourth position, of the form yddd, where y is
the last digit of the year and ddd is the day number within
the year. So, if 2.5 were released today, it would be
2.5.0.8182.

Parameterized test methods can now be generic and NUnit will
provide an appropriate specialization of the method for each
set of parameters provided. This is actually of limited 
utility by itself, but will be more useful in combination with
the support for generic fixtures I'm currently working on.
