Order of log levels

[marciniwanicki]

The current order of log levels:

public enum LogLevel: Int {
    case info
    case verbose
    case warning
    case error
}

Having those levels is nice as it allows the client code to decide how much information should be logged (or presented to the users).

The order of log levels is smoothly distributed between the most verbose (like verbose, trace or debug) and critical (error or critical etc).

I think the info and verbose cases could be swapped to allow uses to specify info if they want to know only general information about the generation process, or verbose if they the want to dig into details.
