newton_interp_1d, a FORTRAN90 code which finds a polynomial interpolant to data using Newton divided differences.

- newton_interp_1d_test.f90, calls all the tests.
- 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 interpolants.
