/** TSTT Mesh Interface Unit Test
 *
 * This program tests TSTT mesh interface functions through the SIDL interface.
 * In a nutshell, the test creates (or accesses) an implementation instance,
 * tells it to load a file (specified on the command line), then calls a
 * number of functions evaluating that mesh.  This test also tests mesh, set
 * and tag creation and evaluation functions.
 *
 * Usage: testcxx <mesh_file_name>
 *
 * Compiling
 * ---------
 * 1. Build your server (your implementation of the TSTT mesh interface) under
 *    SIDL/Babel and put it in a library in the Babel-generated server directory,
 *    ${SERVER_DIR}/libimpl.so.  Any include files needed to instantiate this
 *    server from applications should also be in that directory.  See note a) below.
 * 2. Change the definition of IMPLEMENTATION_CLASS below to be the
 *    namespace-qualified name of your implementation class.  This definition is
 *    used in the main to instantiate the server using the SIDL _create function, e.g.
 *    .   TSTTB::Mesh mesh = IMPLEMENTATION_CLASS._create();
 *    (we put the definition of IMPLEMENTATION_CLASS at the top of this file so that
 *    you don't have to understand the rest of the source code to use this test).  See
 *    note b) below.
 * 3. Include the file(s) needed which declare the implementation's namespace and
 *    class
 * 4. Compile this test file to an object file:
 *        g++ -fpic -I. -I${BABEL}/include -I${SERVER_DIR} -c testcxx.cpp
 * 5. Link the application:
 *        g++ -o testcxx testcxx.o -ltest -L${BABEL_LIBS} -lsidl
 *
 * Notes
 * -----
 * a) The files don't absolutely need to be arranged as described above.  For
 *    example, some projects put their custom implementation files somewhere besides
 *    ${SERVER_DIR}, to keep them separate from Babel-generated files.
 * b) This test assumes interface instances are created using a direct call to the
 *    SIDL _create() function for that class.  Another way to do this would be to
 *    call a factory linked into the test.  To change the method used to construct
 *    the interface instance for this test, see the use of IMPLEMENTATION_CLASS towards
 *    the end of this file.
