@simonp0420 , @kagalenko-m-b

I've just pushed a new version.

  • better algorithm for the Jacobi theta functions
  • Jacobi theta function with characteristics (it generalizes the four Jacobi theta functions)
  • Based on the Jacobi theta function with characteristics, I redefined _jtheta1dash0, the derivative at 0 of the first Jacobi theta function

The third point has caused a problem: the test of the theta-S Neville function with extended precision has failed, because of a small imaginary part in the result while this result should be a real number. I added atol = 1e-15 in @approx in order that the test succeeded.
