Support for haplotype-aware indexing and higher-order indexes in VG.

  • Node mappings for using separate sets of node identifiers for graph transformations and locate() queries.
    • Intended for graphs pruned with vg prune --unfold-paths, which replaces complex subgraphs with subgraphs that only contain specific paths.
    • Build a path graph for the unfolded graph but create an index that maps to the original graph.
  • Support for 4 doubling steps (paths of length up to 256).
  • Optionally specify a sample period instead of always sampling the initial offsets of the original nodes.
