sTiles: Tile-Based Sparse Cholesky Factorization and Selected Inverse

Interface to the 'sTiles' framework for tile-based sparse Cholesky factorization: log-determinants, selected inverse (marginal variances) and triangular solves, with symbolic reuse so that repeated factorization of matrices sharing one sparsity pattern pays the ordering cost only once, as in a hyperparameter sweep. The compiled glue in this package resolves its symbols at run time against the 'sTiles' solver library ('libstiles'), which is a separate component distributed under its own terms and is not part of this package. Install it once with 'sTiles_install_library()', or point the package at a copy you already have with the 'STILES_LIB' environment variable.
