** \brief An OutputStream adapter for the Java bindings
**
** An OutputStream adapter for the Java bindings. This works with a lot
** of help from SWIG, and custom typemaps in the ".i" SWIG interface files
** for CVC4. The basic idea is that, when a CVC4 function with a
** std::ostream& parameter is called, a Java-side binding is generated
** taking a java.io.OutputStream. Now, the problem is that std::ostream
** has no Java equivalent, and java.io.OutputStream has no C++ equivalent,
** so we use this class (which exists on both sides) as the go-between.
** The wrapper connecting the Java function (taking an OutputStream) and
** the C++ function (taking an ostream) creates a JavaOutputStreamAdapter,
** and call the C++ function with the stringstream inside. After the call,
** the generated stream material is collected and output to the Java-side
** OutputStream.
