blatent 0.1.3

• Regenerated src/RcppExports.cpp (and related auto-generated files) with Rcpp 1.1.1 so that internal Rf_error() calls are emitted in the guarded (Rf_error)(...) form, per the Rcpp/CRAN maintainer request. No user-visible behavior change.
• Bumped minimum Rcpp version to >= 1.1.1 in Imports.
