• add summary() and print() functions
• add deconvolve() function to perform analytically deconvolution
• add standardized PSD and false alarm probability to spec.fft-function
• spec.fft handles NA-values by zero padding and simple energy recovery.
• enhance calculation speed by multithreaded BLAS (must be replaced by user)
