TODO list:

- add autotools files to compile (I have only compiled it under enchants tree).
- add a configuration file to hold the user preferences on which checker to use for each language.
- add the preprocessor tags to compile in other operating systems other than Linux and test.
- add support for LanguageTool and adapt the code to deal with a checker for multiple languages. 
- review the code and check for bugs and memory leaks.
