Tester Class

A Tester class was created to contain all the test routines - all the functions in the test_ibcp.cpp source file were put into this new class.  The class definition was put into the new test_ibcp.h header file.  The main test function was split into two functions: the constructor for the Tester class, which will be given the list of command line arguments and will be parsed for test options, and a run function that will run the testing.

Once a Tester instance is created, the caller can check the status.  There will be a function for checking if errors occurred with any command line test arguments, a function to get an error message if an error occurred, and a function to check if there were any test arguments specified.  If there are test options, the run function can then be called.

The code to initialize the static Token data, create a table instance and output any errors, and create a translator instance was moved from the main function to the tester run function along with the output of the GPL header (which is now only output if no error occurs during startup).

The main() function now only handles the command line arguments - outputting the version information if the version option was specified (if this was the only option specified), otherwise creating a tester instance, checking for test argument errors, checking if there are any tests arguments, outputting the usage message if not or running the tester if there are (outputting a message if an error occurs during the test).  If the run function returns false, an error occurred during testing (like it could not open the test file specified) and the error message access function is used to get the message to output.

The tester argument parser in the constructor loops over all arguments looking for valid test options.  It verifies that only one test argument is specified, but ignores non-test arguments.  Right now, if valid test arguments are specified, the test will be run and the program will exit.  If other options are also specified (say version or an invalid option), they are currently ignored.  This will be taken care of next with a new command line class.
