Progress: continuing development, updated test example, added language testing, miscellaneous fixes

Did some testing and made sure the test example was working.

Added some languages for testing.
- I specifically added japanese as a language to test for error messages because it is so different from english.
- It is not practical to implement the error messages class for many languages right now because I expect major refactoring as I continue coding.
- Another simple language test is added, testing the languages: russian, spanish, japanese, and english.

More work done on in developing the database.

Other fixes and changes.
