sdcHierarchies 0.23.02026-03-19

• Feature: hier_create_ids(): Added this new utility to map microdata to hierarchical grid levels using high-performance integer-based indexing.
• Feture: enhanced hier_grid():
  • Added the add_contributing_cells argument to enable faster data aggregation.
  • Improved the handling of “bogus” structures; setting add_dups = FALSE now correctly prunes redundant parent nodes across multiple dimensions.
• Feature: Performance improvements:
  • Refactored core tree-traversal logic in Rcpp code for significant speed improvements
  • Added new internal Rcpp utility functions (rcpp_get_sort_order(), rcpp_tree_to_matrix(), rcpp_get_leaves_list()) to improve leaf-node identification and path encoding.
• Bugfix: hier_app(): Fixed a synchronization bug in the shinyTree interface that occurred when collapsing or interacting with nodes.
• Update: Extended unit tests for hier_grid() to ensure stability across different edge cases.
• Update: Improved and extended the package vignette to cover new features.
