298c83e71c 1F1: improve method selection logic. 
The only really gross failures now are exceptions due to non-convergence.
There are also some large errors in certain regions - notable b large and negative, a large and positive, we don't currently have a method that works for that, need to investigate Miller type methods.

2a0f5f111c 1F1: more changes to negative a and b domain. 
* Bessel approximation is now good for b-2a <= 0 via Tricomi's relations.
* Selection condition based on convergence is now more rigorous, or at least more conservative.  But...
* Error rates are much higher because a poorly converging bessel approximation has slightly less cancellation than the generic series.  Hopefully this can be fixed via https://dlmf.nist.gov/13.13.  And...
* We need to rewrite these new versions to use recurrence relations on the Bessel functions (but these need to be backwards, so we would calculate and cache say 50 evaluations, then the next 50 and so on).  And...
* Bessel approximations can underflow spuriously when b is large.... really need a log_bessel_j to fix this as we will be multiplying by tgamma(b).

b4ec109b83 tanh_sinh: change calculation method used for scaling ranges: 
"naive" method is prone to generating a point at the endpoint if the endpoint is large, subtract scaled complement from the endpoint instead.
Open questions:
1) Can this still fail if the endpoint is a very large value?  For example if we have endpoints of [+large, +larger] where the difference between them is small?
2) Do we still need the asserts, or should they be replaced by some other check?
3) If the endpoints are replaced by some other check we could either massage the position to be one representable value below the endpoint, or else simply return 0.  The former risks evaluating at the same point over and over as we go down levels, the latter would seem to be incorrect for functions which do not go to zero at the endpoint.

4fc8d43b4b make move constructor and operator= noexcept 
This change helps the polynomial class play well with STL
containers.

> If the move constructor for an element type in a container
> is not noexcept then the container will use the copy constructor rather
> than the move constructor -- HIC++ Version 4.0

Benchmarking shows that the number of calls to copy constructor
are reduced.

136e7411f5 Adaptive Trapezoidal Quadrature 
This routine estimates the definite integral of a function f.
Assuming that f is periodic, it can be shown that this routine converges exponentially fast.
In fact, the test cases given exhibit exponential convergence with decreasing stepsize.

A potential improvement is using the Bulirsch sequence rather than the Romberg sequence to schedule the refinements.
However, the convergence is so rapid for functions of the class specified above that there seems to be no need at present.

This code is cppcheck clean, and runs successfully under AddressSanitizer and UndefinedBehaviorSanitizer.

fee20ab932 Given a function f, known at evenly spaced samples y_j = f(a + jh), 
this function constructs an interpolant using compactly supported cubic b splines.
The advantage of using splines of compact support over traditional cubic splines
is that compact support makes the splines well-conditioned.

The interpolant is constructed in O(N) time and can be evaluated in constant time.
Its error is O(h^4), and obeys the interpolating condition s(x_j) = f(x_j) for all samples.
In addition, f' can be estimated from s', albeit with lower accuracy.

This routine is cppcheck clean, and is clean under AddressSanitizer and MemorySanitizer.
