Detailed Description
Base class for an object that allocates data in some way.
This class is meant to be derived from, the ctor of the derived class should set up the data pointer and size while it's dtor should destroy it. The destructor needs to be overridden for this to happen.
The data is allocated on constuction of the object and deallocated on destruction.
