* BOOST_MATH_EXPORT on the integrator class templates, trapezoidal and
the wavelet transform, plus the interpolator class templates and their
stream operators
* Adds the quadrature and interpolator headers to the module interface
unit (cardinal_trigonometric and the deprecated boost::math namespace
shims stay textual only)
* Module test harness gains git_issue_898,
cardinal_quadratic_b_spline_test and whittaker_shannon_test
where max_left_index/max_right_index may go to zero if the function being integrated overflows the FP type being used across nearly all of it's range. Fixes https://github.com/boostorg/math/issues/898
