TEST_INTERP_1D_TEST
  C++ version
  Test the TEST_INTERP_1D library.
  The R8LIB library is needed.

TEST01
  Print the title of each function.

  There are 8 functions available:
  Index  Title

   1  f(x) = steps -1/2/1 at [0,1/3], [1/3,4/5], [4/5,1].
   2  f(x) = (1-3x), x < 1/3 (6x-2) if 1/3 < x
   3  f(x) = x (10*x-1) (5x-2) (5x-2) (4x-3.4) (x-1)
   4  f(x) = atan ( 40 * x - 15 )
   5  f(x) = cos(7*x)+5*cos(11.2*x)-2*cos(14*x)+5*cos(31.5*x)+7*cos(63*x).
   6  f(x) = exp ( - ( 4*x-1 )^2 )
   7  f(x) = exp ( 2 x ) if x < 0.5, 0 otherwise
   8  f(x) = 1 / ( 1 + ( 10 * (x-1/2) )^2 )

TEST_INTERP_1D_TEST02
  Use P00_F to sample each function.
