Adding New Languages

New languages are defined by adding them to Hloc.hs.

You will need to define the following for a new language

• single line comment characters
• multi line comment pairs
• exceptions
• file extensions

Submit a PR to update languages as well as adding a test to languageTests in Test.hs.
