Title: Added ode4(), ode4ms(), and general multistep ODE solvers.

This adds two of the fixed-step solvers, and add small fixes to the existing solvers for argument types and typing workarounds which are probably bugs and need a testcase.

The Rosenbrock fixed-step solver for stiff systems is still in work. Testing indicates that there are problems in my translation from MATLAB that is driving the solution to my (stable) test system unstable.
