Great job. May I download it?

My proposition is just an simple example, of the design. If I can say
something about my design style, I have other more complicated math example
http://knnl.sf.net and description is 
http://accu.org/var/uploads/journals/overload74.pdf from page 23.
Unfortunately library is not on the Boost licence. Maybe next version I
will prepare with Boost licence.

In preparation I have adaptive Runge-Kutta (4,5) method.

I am looking for some tips if there is possible to make generalized
Runge-Kutta method. In math books there is an algorithm how to calculate
all coefficients for RK algorithm, but the point is that in templates I
need to use only integral types, so I need to have all coefficients split
in to the two parts: numerator and denominator, and prepare dedicated
algorithm to work with such a fractional numbers to calculate RK
coefficients in compile time. Otherwise it is easy to do algorithm which
prepares coefficients in constructor of the solver, because double numbers
are possible.

This is the reason why I want to join somewhere - I want to exchange
experience on the generative design for the math purpose.

Regards and thanks.
