Added data for H^10_1(1,y) without gauge transformation to avoid an error of linear interpolation
of , e.g., tk_ode_assert.get_linear_linear_interpolation_value("h",3.97)*exp(3.97)*3.97^10.
Use tk_ode_assert.get_linear_interpolation_value("hn",3.97) instead.

tk_ode_assert.output_relative_error("h2","t.txt" | zoom=10^4301)
generates tmp-rerror.txt of the relative error of H^k_n. See tk_ode_assert.usage_assert() for details.

Branch: MAIN

A C program generator for a numerical solver of ODE with some heuristics to avoid instability.
Example:  Solving the Airy differential equation:
--> load("tk_ode_by_mpfr.rr");
--> Code=tk_ode_by_mpfr.code_solve_ode_by_rk4_with_defuse([[0,1],[t,0]],
     0,[0.355028053887817,-0.258819403792807],10.1 | h=0.001)$
-->  util_write_string_to_a_file("tmp-test.c",Code)$
