* OBJECT-ORIENTED FEATURES

* These extensions provide a more object-oriented interface to C++

*
* I have generalized these extensions to make them more general purpose
* and to resolve object-ownership problems.
*
* The approach here is very similar to the Python module :
* 1. All of the original methods are placed into a single
* package like before except that a 'c' is appended to the
* package name.
*
* 2. All methods and function calls are wrapped with a new
* perl function. While possibly inefficient this allows
* us to catch complex function arguments (which are hard to
* track otherwise).
*
* 3. Classes are represented as tied-hashes in a manner similar
* to Gary Holt's extension. This allows us to access
* member data.
*
* 4. Stand-alone (global) C functions are modified to take
* tied hashes as arguments for complex datatypes (if
* appropriate).
*
* 5. Global variables involving a class/struct is encapsulated
* in a tied hash.
