%description
Implements the Shimazaki-Shinomoto method for optimizing the bin width of
histograms and the bandwidth of kernel density estimators.  The framework
minimizes the expected Mean Integrated Squared Error (MISE) and supports
both 1D and 2D distributions, fixed and locally adaptive estimators,
bootstrap confidence intervals, and 'OpenMP'-accelerated 'C++' 'backends'.
Ideally suited for time-dependent rate estimation and identifying
intrinsic data structures. For more details see Shimazaki and Shinomoto
(2007) <doi:10.1162/neco.2007.19.6.1503> and Shimazaki and Shinomoto
(2010) <doi:10.1007/s10827-009-0180-4>.
