/** \brief Set options for DirectLineSearchArmQuad_Strategy from a
* OptionsFromStream object.
*
* The default options group name is DirectLineSearchArmQuad.
*
* The options group is:
*
\begin{verbatim}
options_group DirectLineSearchArmQuad {
slope_frac = ?;
min_frac_step = ?:
max_frac_step = ?;
max_ls_iter = ?;
max_out_ls_iter = ?;
}
\end{verbatim}
*
* \begin{description}
* \item[slope_frac] Fraction of intial decent slope of merit
* function required by armijo test. Mapps to eta in linesearch
* algorithm. Must be in the range [0, 1].
* Example: slope_frac = 1.0e-4;
* \item[min_frac_step] Minimum fractional change in the step length
* per linesearch iteration. Mapps to min_frac in the linesearch
* algorithm. Must be in the range (0, 1].
* Example: min_frac_step = 0.1;
* \item[max_frac_step] Maximum fractional change in the step length
* per linesearch iteration. Mapps to max_frac in the linesearch
* algorithm. Must be in the range (0, 1]. Note that
* max_frac_step must be greater than min_frac_step.
* Example: min_frac_step = 0.5;
* \item[max_ls_iter] The maximum number of linesearch iterations
* to take before giving up and declaring a line search failure.
* Mapps to max_ls_iter in linesearch algorithm.
* Example: max_ls_iter = 20.
* \item[max_out_ls_iter] A flag to max out on line search iterations.
* Mostly just used for debugging, not very useful in general.
