rNFFT

Writing an R wrapper for the NFFT library (nonequispaced nodes Fast Fourier Transform)

See: https://github.com/NFFT/nfft https://tu-chemnitz.de/~potts/nfft/

Currently, this is not in anything approaching a working state. I think the issue may be that I need to handle this with external pointers (as fftw does but fftwtools doesn't).

NEWS (07/21/19): I fixed a thing so now the test function works. From here, completing the package should be straightforward once I put a little work in (or if anybody looks at the repo, they can take over from here).

NEWS (07/22/19): I have implemented the 1D functions, including the cosine and sine transforms. I don't have the 2D functions or the 3D functions. I do not have the ability to alter the flags in there yet, either. However, they can be specified in the future. Caveat emptor. EDIT: I have this working on Travis now, the issue was telling it to run autoconf (I thought the R build process did that automatically, but it doesn't).
