Version 0-1.17 of the Rborist package is building
successfully on CRAN. This is the last of the 0-1 series; future versions will
instead employ a more conventional API numbering scheme.

Two new command-line options have been introduced. Option nThread
permits limiting the number of OpenMP threads employed in parallel regions of
code. Option “oob” constrains prediction to out-of-bag samples, facilitating
the computation of permutation-based variable importance.

The IR bridge has been considerably simplified. In particular, much of the
heavy lifting involved in blocking data.frame objects is now
accomplished by a single call to the data.table library.
Package dependencies remain at two, now Rcpp and
data.table.

In addition to bug repairs, memory footprint has also been diminished.
Copies from core data structures to their R counterparts are now buffered,
greatly smoothing a spike in resource usage encountered following training.

Special thanks to the CRAN team for their patience and their continuing
effort to improve build standards.
