# Receives a variety of objects for logging.
# LogSanity itself sends Hashes which are formatted with #to_json.
# Other than Strings, will embed any other object into a jsonified hash.
# Strings are a bit of a special case and by default continue to be formatted
# with whatever Rails' formatter originally was. As such, it can be configured
# using `config.log_formatter`. This keeps exception backtraces and other
# various logs still as Strings. If you prefer Strings to also be turned into
# jsonified messages, set `config.logsanity.json_strings = true`.
