Demonstrate how to do basic auto-generation of C or C++ code or headers using Python!

To run this script:
    ./autogenerate_c_or_cpp_code.py

...then examine the contents of "autogenerated/myheader.h", which this script just auto-generated!

To produce this:

struct myStruct {

    float f1;
};
```

do this, for example...
