Title: Piecewise Geodesic Smoothing for Spherical Data
Version: 0.1.3
Description: Fitting a smooth path to a given set of noisy spherical
        data observed at known time points. It implements a piecewise
        geodesic curve fitting method on the unit sphere based on a
        velocity-based penalization scheme. The proposed approach is
        implemented using the Riemannian block coordinate descent
        algorithm. To understand the method and algorithm, one can
        refer to Bak, K. Y., Shin, J. K., & Koo, J. Y. (2023)
        <doi:10.1080/02664763.2022.2054962> for the case of order 1.
        Additionally, this package includes various functions necessary
        for handling spherical data.
