This function aims to solve the general multi-stage model
with piecewise constant parameters approximatively
by integrating the characteristic equations with Euler's method.
For sufficiently small time intervalls, this approximation often
yields reasonable results.
Small time intervals can either be provided explicitly with many columns
in argument t
.
An alternative is the optional parameter innerSteps
.

Positive integer.
To improve accuracy, each time interval is internally

The output list contains all used arguments of the
parameterList
and vectors of the model results for
hazard and logarithm of the survival function
for each row of the input.
