+ * src/Rcpp/ComplexVector.h: new class Rcpp::ComplexVector
+ to manage ... complex vectors (CPLXSXP)
+ * src/ComplexVector.cpp: implementation
+ * inst/unitTests/runit.ComplexVector.R: unit tests
+
* src/Rcpp/Promise.h: new class Rcpp::Promise to manage
promises (PROMSXP). only read access so far (no way to force
the promise)
