 *
 * SWIG typemaps for std::vector
 * C# implementation
 * The C# wrapper is made to look and feel like a typesafe C# System.Collections.ArrayList
 * All the methods in IList are defined, but we don't derive from IList as this is a typesafe collection.
 * Warning: heavy macro usage in this file. Use swig -E to get a sane view on the real file contents!
 *
 * Very often the C# generated code will not compile as the C++ template type is not the same as the C# 
 * proxy type, so use the SWIG_STD_VECTOR_SPECIALIZE or SWIG_STD_VECTOR_SPECIALIZE_MINIMUM macro, eg
 *
 *   SWIG_STD_VECTOR_SPECIALIZE_MINIMUM(Klass, SomeNamespace::Klass)
 *   %template(VectKlass) std::vector<SomeNamespace::Klass>;
