Detailed Description

Helper for packing/unpacking a PackedContainer to/from a stream.

This object should be created with the packing parameters to use. After that, call the read or write methods. These are all templated methods taking a vector<U> as input; this should be the vector contained within the PackedContainer. Additional overloads are supplied taking vector<vector<U> >. These read/write the element count, then call read/write for each element of the vector. This should allow for arbitrary vector nesting.

The methods are also templated on the input/output stream. This should support operator<< and operator>> for a uint32_t; a ROOT TBuffer will satisfy this.
