Eventually this directory will contain a bunch of test programs.
Unfortunately, I haven't figured out a good way to set this
up due to huge variations in the way software might be installed
on different machines. 

For now there are two files that test the SWIG parser.

test.i   - Contains SWIG declarations that should parse
           correctly.   SWIG may generate warnings, but
           it should not generate parse errors or syntax
           errors.

errors.i - Some errors that should be caught by the SWIG
           parser.
