fix initialization with external stepper ( #215 )
...

Improvement to Order Selection, Error approximation in the ABM stepper ( #218 )
...
* improves the order selection and modifies the error estimation accordingly
- assumes constant stepsize for the next step to approximate error
- moves the complete order adjustment to the class order_adjustment
- slight changes to adaptive_adams_coefficients
* changed the commit according to the requests and comments

Switch fabs for std::abs
...
- controlled_adams_bashforth_moulton.hpp, adaptive_adams_coefficients.hpp and pid_step_adjuster.hpp extract absolute values using fabs() without a namespace qualifier
- if the integration value type is not double then this can cause problems, since fabs() is not required to have a long double overload. In such cases it is safer to use std::abs, and also this matches the rest of the odeint-v2 codebase

...
A bug introduced with the recent max_dt facility prevented the rosenbrock
controller to increase step size in most cases (if max_dt=0). This is fixed
now, and a regression test case has been added.

BS stepper: correct exponents for optimal h
...
Becoming suspicious by the difference of the exponents used for computing the
new step size in the BS and BS denseout stepper (see
0f943fbf8b303a8083876bb1fba677d4c4677417) I checked again the Hairer book and
I'm now convinced there was a mistake in our implementation and both
steppers should use 1/(2*k+1) as exponent. The background is the this exponent
represents the order of the error of the k-th iteration, and this order is
always 2k+1, independent of the interval_sequence. This error is computed from
the difference of the k-th and k-1 - th iteration, which have the orders 2k+2
2k respectively, which means the computed error has order 2k+1.

addressing #184 , simple fix is to also reset m_current_k_opt and therefore
make sure the loop doesnt overshoot.
