newton_interp_1d, a C++ code which finds a polynomial interpolant to data using Newton divided differences.

- newton_interp_1d_test.cpp, a sample calling program.
- newton_interp_1d_test.sh, runs all the tests.
- newton_interp_1d_test.txt, the output file.

The code generates some plots of the data and approximants.
