Changes in RProtoBuf version 0.3.1 (2013-09-13)
Added support for setting and getting 64-bit integer types as character strings of decimal integers to work around R's lack of native 64-bit integer types.
Added better error handling, documentation, and tests to the extensions support (getExtension and setExtension).
Add support to P for returning extension descriptors.
Improved error messages to include field names when invalid fields are specified to protocol buffer messages with new, update, etc.
Improved configure to detect and pass
-std=c++0xif it is available to enable long long 64-bit integer support in Rcpp.
Improved configure in the case when pkg-config is not available or does not know about the google protocol buffer includes.
Replaced newly deprecated Rcpp macros with a simplified macro functionality to avoid warnings on the latest development version of Rcpp.
