STARTING TO WORK ON 0.5
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
Fix rst definition list formatting 

Wasn't rendering correctly online: 'Optional classifiers may follow the term on the same line, each after an inline " : " (space, colon, space).'
