#1352: Lomb-Scargle periodogram

Comment(by pschella):

 The method used to calculate the periodogram is described in a paper by
 R.H.D. Townsend (http://arxiv.org/abs/1007.1658).
 It basically refactors the Lomb-Scargle equation to allow it to be
 calculated using only a single pass through the input data for each
 frequency (as supposed to two times in the straightforward calculation).
 As mentioned there the algorithm is also trivially parallelizable and this
 could easily be done with OpenMP or CUDA/OpenCL (just let me know if you
 want that as well).
