humanize

public static String humanize(Message m)

Humanizes the message in order to be correctly displayed. Like handling methods, this is a wrapper to call humanize just once and avoid code duplication. toString() could have be used, but we didn't want to mess with it since we wanted to reserve it for debug purposes.

m - The message to be humanized

Returns:

A string ready to be printed
