This version changes how use the std namespace: all usage is now
properly prefixed. Likewise, we now define R_NO_REMAP to not
let R define utility functions as length() or
error() which occassionally creates trouble with other include
files -- so now use the more explicit forms Rf_length(),
Rf_error() etc. Also, starting from this release, C++ class
documentation created by Doxygen is included; it can also be seen from my box
as both browsable
html and a pdf file.
Lastly, this version also adds a minor correction to the Windows build
(spotted by Uwe and Simon).
