collatz_polynomial_test():
  Python version: 3.6.9
  Test collatz_polynomial()

collatz_polynomial_next_test():
  collatz_polynomial_next() returns the next polynomial
  in a Collatz sequence.

  p0(x) = x^2+1
  p1(x) = x^3+x^2+x

  p0(x) = x^5+x^4+x^2
  p1(x) = x^4+x^3+x

  p0(x) = 1
  p1(x) = 1

collatz_polynomial_sequence_test():
  collatz_polynomial_sequence() returns the sequence of
  Collatz polynomials generated from a given starting polynomial.

i4vec_is_binary_test():
  i4vec_is_binary() is TRUE if an I4VEC only contains
  0 or 1 entries.

[0 0 0]
  X is binary

[1 0 1]
  X is binary

[0 2 1]
  X is NOT binary.

polynomial_degree_test():
  polynomial_degree() returns the degree of an polynomial.

  polynomial coefficient vector c:
[0 1 0 3 4 0 6 7 0 0 0]

  p(x) = 7*x^7+6*x^6+4*x^4+3*x^3+x

  The polynomial degree = 7
