Change Log:

v0.2.0.0:

• authenticate function now returns MonadIO m => m PamRetCode rather than IO (Either Int ())
• authSuccess :: PamRetCode -> Bool added which checks if the given PamRetCode is PamSuccess or not
• whenSuccess :: MonadIO m => PamRetCode -> m PamRetCode -> m PamRetCode added, which returns the second argument if the given response code is PamSuccess, otherwise it returns the given response code (useful for continuing only if the PAM action succeeded).
• pamCodeToMessage, pamCodeToCDefine and pamCodeDetails now take a PamRetCode rather than an Int
• checkAccount function has now been implemented
• Switched to PVP versioning
• Some documentation added
