'''Command window types for SublimeHaskell.
SublimeText has several different "command" classes. The two important ones are `sublime_plugin.TextCommand` and
`sublime_plugin.WindowCommand`. These two classes have `is_enabled` and `is_visible` methods, which SublimeHaskell
overrides to enable commands if the source code is Haskell source.
