 This is a prototype for marshalling value-like data in Java into flattened
 storage using reflection and Unsafe get and put.  In its current state it
 should provide a safe, slow, and perhaps memory-leaky way to render Java
 data structures into a form immediately accessible from other unsafe
 programming languages (C and Fortran) or GPUs.

 Possible directions for improvement include performance enhancements (for
 example, custom-generated bytecodes), automatic generation of layout
 specifications using SWIG, using the flattened representation as the preferred
 storage for Java data structures (e.g., for an array of complex).
