 In my research field of Astronomy we often encounter timeseries with
 uneven temporal sampling.
 Such timeseries cannot be analyzed with the standard Fast Fourier
 Transform.
 The most frequently used tool to analyze such timeseries is the Lomb-
 Scargle periodogram, developed by Lomb (1976) and further extended by
 Scargle (1982).
 Currently, to my knowledge, SciPy does not include a routine to calculate
 such periodograms.
 Therefore I would like to contribute the following code which efficiently
 calculates the periodogram.
 It is licensed under the terms of the BSD open source license but I would
 be willing to release it under any other language if this is necessary for
 possible inclusion with SciPy.
 The routine is written in Fortran 95 and wrapped with f2py, but I would be
 willing to rewrite it in C if required.
 Also included is a Python test script.
 Please provide me with any feedback in case you would consider including
 this.
