10e6f0d68f Lambert W: Add tests near the singularity. 
Fix a couple of minor issues in the implementation to improve error rates.
NB: errors very near the singularity are still very high - this is an intrinsic property of the function - we are solving z = w exp(w) for w, but there are actually a wide range of w values which satisfy the equation once we get very close to the singularity.

c275bf655e Refactor the polynomial addition function 
* Remove in-loop calls to push_back thus eliminating the
  possibility of multiple reallocations of memory to the
  underlying vector.
* Remove redundant `sign` parameter from the addition method
* Delete the unused `detail::identity` struct

72c56026f9 tanh_sinh: improve asserts on internal logic

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.
