Right on the heels of release 0.2.1 of RcppCNPy, a new version 0.2.2 is now on CRAN. RcppCNPy uses the CNPY library by Carl Rogers to provide R with easy read and write access to NumPy files. The reason for the new version that I had experimented with a different way to test endianness (as needed for the NumPy file headers) but accidentally sent an interim tarball to CRAN which still wanted to include
endian.h promptly breaking Windows
builds. So now we do something even simpler and just rely on the (even more
complete) test for endianness when R is built, which prevents all sorts of
complications for us and builds everywhere (with thanks to Brian Ripley for the suggestion).
While we were at it, we also added a new unit test.
Full changes are listed below.

Switched to using the result from the compile-time configuration for R to determine big or little endian (as needed for the

CRANberries also provides a diffstat report for 0.2.2 relative to 0.2.1. As always, feedback is welcome and the rcpp-devel mailing list off the R-Forge page for Rcpp is the best place to start a discussion.
