%description
Provides methods for fast computation of running sample statistics for
time series. These include: (1) mean, (2) standard deviation, and (3)
variance over a fixed-length window of time-series, (4) correlation, (5)
covariance, and (6) Euclidean distance (L2 norm) between short-time
pattern and time-series. Implemented methods utilize Convolution Theorem
to compute convolutions via Fast Fourier Transform (FFT).
