Providing zero-copy read access to the table columns and tree arrays?

[gregorgorjanc]

Jerome suggested that this would be the killer feature that other R packages could build on. I presume R will allow you to expose an array of (e.g.) int32 as a vector?

Have to explore this option ...

See how this is done for Python-C low-level interface https://github.com/tskit-dev/tskit/blob/python/_tskitmodule.c --> Notes on this are in https://github.com/HighlanderLab/RcppTskit/blob/gregorgorjanc/issue49/RcppTskit/notes_pkg_dev.Rmd, as well as notes on a possible ALTREP approach
