 Description: Provides nFunction and nClass for function and class definitions for which C++ can be automatically generated, or used in combination with other C++.  Supports linear algebra by code-generating C++ that uses the Eigen library. Supports automatic differentiation by code-generating C++ that uses the CppAD library.  Support for parallelization is planned by code-generating C++ that uses Intel Threading Building Blocks (TBB).
