ENH: NFFT keyword is now functional in multitaper methods, and normalized bandwidth NW parameter is now accepted
ENH: make separate tapered_spectra method to tease out some commonality between PSD and CSD computations
ENH: work in progress--detection of harmonic lines in spectrum
BF: minor bug in output of tapered_spectra
BF: elementwise product of the empty sequence returned a sneaky float (needed int)
small speedup for FFT of real-value signals
undo real-series FFT speed tweak causing hidden 
problems
ENH: speed up (50x!!) tridisolve with Cython
BF: cross-spectral density matrices were not 
Hermitian! This was due to a quirk in the order of
coordinates returned by tril_indices() and 
triu_indices(), IE they do not index symmetric 
matrix locations.
Thomson's F-test for harmonic components, plus
some nosetests for the method
demo for the harmonic test method
BF: zeros required for CSD transposing
BF: put cython extension in the right location
ENH: change up adaptive weighting method, 
probably fixes bugs, and should improve 
convergence for a high number of points
Demo for computing baseband complex demodulate 
using multiple Slepian tapers
BF: other sneaky integer problem
Typo in demo
Typos: removed print() and revised notes-to-self
a couple tests re: 42eae1dcdc8ecdef13fcab4b32d7be3fc2a46a20
a couple more tests re: 42eae1dcdc8ecdef13fcab4b32d7be3fc2a46a20
