| Testcase for UnivariateRealSolver.
Because Brent-Dekker is guaranteed to converge in less than the default
maximum iteration count due to bisection fallback, it is quite hard to
debug. I include measured iteration counts plus one in order to detect
regressions. On average Brent-Dekker should use 4..5 iterations for the
default absolute accuracy of 10E-8 for sinus and the quintic function around
zero, and 5..10 iterations for the other zeros.
