clenshaw_curtis_rule_test():
  Python version: 3.8.10
  Test clenshaw_curtis_rule().

clenshaw_curtis_rule():
  Compute a Clenshaw Curtis rule for approximating
    Integral ( A <= x <= B ) f(x) dx
  of order N.

  The user specifies N, A, B, and FILENAME.

  N is the number of points:
  A is the left endpoint
  B is the right endpoint
  FILENAME is used to generate 3 files:

    filename_w.txt - the weight file
    filename_x.txt - the abscissa file.
    filename_r.txt - the region file.

  N =  5
  A =  -1.0
  B =  1.0
  FILENAME = "cc_o5".
  abscissas saved to "cc_o5_x.txt"
  weights saved to "cc_o5_w.txt"
  region saved to "cc_o5_r.txt"
