     *

     * \brief ODE Iterator with given evaluation points. The value type of this iterator is the state type of the stepper.
 | 
						|
     *
 | 
						|
     * Implements an iterator representing the solution of an ODE from *t_start
 | 
						|
     * to *t_end evaluated at time points given by the sequence t_start to t_end.
 | 
						|
     * t_start and t_end are iterators representing a sequence of time points
 | 
						|
     * where the solution of the ODE should be evaluated.
 | 
						|
     * After each iteration the iterator dereferences to the state x at the next
 | 
						|
     * time *t_start++ until t_end is reached.
 | 
						|
     * This iterator can be used with Steppers, ControlledSteppers and
 | 
						|
     * DenseOutputSteppers and it always makes use of the all the given steppers
 | 
						|
     * capabilities. A for_each over such an iterator range behaves similar to
 | 
						|
     * the integrate_times routine.
 | 
						|
     *
 | 
						|
     * times_iterator is a model of single-pass iterator.
 | 
						|
     *
 | 
						|
     * The value type of this iterator is the state type of the stepper. Hence one can only access the state and not the current time.
 | 
						|
     *
 | 
						|
     * \tparam Stepper The stepper type which should be used during the iteration.
 | 
						|
     * \tparam System The type of the system function (ODE) which should be solved.
 | 
						|
     * \tparam State The state type of the ODE.
 | 
						|
     * \tparam TimeIterator The iterator type for the sequence of time points.
