hlint :: [String] -> IO [Suggestion]
This function takes a list of command line arguments, and returns the given suggestions.
To see a list of arguments type hlint --help at the console.
This function writes to the stdout/stderr streams, unless --quiet is specified.
As an example:
do hints <- hlint ["src", "--ignore=Use map","--quiet"]
when (length hints > 3) $ error "Too many hints!"
suggestionLocation :: Suggestion -> SrcLoc
From a suggestion, extract the file location it refers to.
suggestionSeverity :: Suggestion -> Severity
From a suggestion, determine how severe it is.
