Runge-Kuttas:
- extra output: number of failed steps (see also 2)
- number of function evaluations + 1 for initial condition
- dense output for cash-karp

other:
- image function for ode.2-D added.
- changed warning printing in FORTRAN code
- common interface for radau and daspk: both can solve systems written as M*dy = f(x,y). daspk can also solve systems written as 0 = g(x,y,dy) (=default for daspk)
