In shoebodh/radialpsd: Calculates Radially Averaged Power Spectrum (periodograms) of a 2D matrix

#'radialpsd: radially averaged periodograms (or r-spectrum) of 2D matrices.
#'
#'This package is based on the methods described by Mugglestone and Rainshaw (1998).
#'The r-spectra are calculated by averaging the fourier coefficients produced by base R's
#'fft() after transforming the cartesian coordinates in to polar. Both omni-directional
#'(i.e. over a circular region defined the distance) and
#' directinal (averaged over a slice defined by an angle +- offset) can be calculated
