This is a test project to make a python numpy version of fast, complex Fourier interpolation, and to use that to perform coherent harmonic summing pulsation searches of PRESTO-style FFTs.

• Fourier interpolation is defined in Eqn. 30 of this paper: https://arxiv.org/pdf/astro-ph/0204349
• PRESTO is the pulsar analysis toolset found here: https://github.com/scottransom/presto
