ODE: Improve time step control

Added a new class Controller containing a collection of different
time step controllers, some of them based on the controllers presented
in Soderlinds "Digital Filters in Adaptive Time-Stepping" (TOMS 2003).

 - Simple:   simple predictive controller
 - Harmonic: simple predictive controller with harmonic damping
 - H0211:    controller from Soderlind
 - H211 PI:  controller from Soderlind

Some simple tests indicate that H211 PI should be a candidate for
the default filter.
