ringSeg 0.1.0

• Initial release.
• RING rank-based, asymptotic distribution-free change-point detection (Zhou & Chen, 2025, IEEE Transactions on Information Theory, doi:10.1109/TIT.2025.3575858): scans a sequence for a single change-point or a changed interval using the weighted (WR), max-type (MR), and generalized (TR) rank statistics, with analytic distribution-free p-values, an optional skewness correction, and optional permutation p-values.
• Main functions: ring_cpd() (data / distance in), rcpd() (rank matrix in), ring_graph() (build the RING k-NN rank graph), and Rise_Rank().
