0011 /** @file skeleton_and_content.hpp
0012  *
0013  *  This header provides facilities that allow the structure of data
0014  *  types (called the "skeleton") to be transmitted and received
0015  *  separately from the content stored in those data types. These
0016  *  facilities are useful when the data in a stable data structure
0017  *  (e.g., a mesh or a graph) will need to be transmitted
0018  *  repeatedly. In this case, transmitting the skeleton only once
0019  *  saves both communication effort (it need not be sent again) and
0020  *  local computation (serialization need only be performed once for
0021  *  the content).
