maint: Continued clean-up of functions in ode/private dir. * AbsRel_Norm.m: Use retval as return variable. Use sumsq() rather than explicit squaring of vector and sum(). Combine multiple lines where possible. * integrate_adaptive.m: Rewrite docstring. Only call starting_stepsize() if InitialStep option is empty. * integrate_const.m: Rewrite docstring. Remove useless commented out code. Combine multiple lines where possible. * integrate_n_steps.m: Rewrite docstring. Remove useless commented out code. Combine multiple lines where possible. * kahan.m: Remove excessive 4-space indentation, use 2-space indentation. * ode_rk_interpolate.m: Use parentheses around condition for switch stmt. Combine multiple lines where possible. * ode_struct_value_check.m: Remove comma from Copyright statement that Octave doesn't use. * odepkg_event_handle.m: Remove comma from Copyright statement that Octave doesn't use. * odepkg_structure_check.m: Remove comma from Copyright statement that Octave doesn't use. * runge_kutta_45_dorpri.m: Remove comma from Copyright statement that Octave doesn't use. Improve docstring. Match variable names in documentation to those in code. * starting_stepsize.m: Rewrite docstring. Use spaces between function name and opening parenthesis.
