/**
This is a very simple class for passing stuff around
in a void pointer. It has the ability to store and query
a type name, so at least there can be user-enforced
type safety.
When setTypeName is called, a char* is created and a copy
of the input argument is taken. This char* is later destroyed
by the Data destructor. The void* dataPtr_ member is not
destroyed, it is just a copy of a pointer.
