Class StreamingFileFromFeatures to read vector-by-vector from a CFeatures object.
The object must be initialized with another CFeatures object. It is upto the derived class to implement specialized functions to return the vector.
Only a subset of the functions defined in StreamingFile.h need to be implemented, as appropriate for the CFeatures object which the class works with.
For example, a derived class based on SimpleFeatures should only implement the get_(type)*_vector() functions, and a class based on StringFeatures should only implement the get_(type)*_string() functions.
