Rusty FITPACK

Rusty FITPACK provides the 1D routines for spline interpolation and fitting in Rust. The functions are translated from the original Fortran77 code FITPACK by Paul Dierckx. This packages provides almost the same interface as the SciPy wrapper for FITPACK. In concrete terms, the package implements five functions, splrep, splev, splder and splev_uniform as well as splder_uniform.
