//--- Include qhull, so it works from with in a C++ source file
//---
//--- In MVC one cannot just do:
//---
//--- extern "C"
//--- {
//--- #include "qhull_a.h"
//--- }
//---
//--- Because qhull_a.h includes math.h, which can not appear
//--- inside a extern "C" declaration.
//---
//--- Maybe that why Numerical recipes in C avoid this problem, by removing
//--- standard include headers from its header files and add them in the
//--- respective source files instead.
