vytools.hpp

VyTools is a C and C++ library which makes often used tasks easier.
The vytools.hpp is for the C++ part. It defines the namespace vyt. All other declarations are in that namespace.
It contains basic types, some utility functions, base classes for non-create, non-assign, referent-counted or copy-on-write classes, exception, a basic stream and a char- and wide string.

Hidden assignment 
struct RefData: public NoAssign
Reference counted data Base class to be used with RefCount
ref Number of references to this data 
RefData()
Default constructor 
virtual ~RefData()
Virtual destructor
