In this exercise you'll be processing log-lines.

Each log line is a string formatted as follows: "[<LEVEL>]: <MESSAGE>".

There are three different log levels:

You have three tasks, each of which will take a log line and ask you to do something with it.

1. Get message from a log line

Implement the LogLineParser.message method to return a log line's message:

LogLineParser.message('[ERROR]: Invalid operation')
// Returns: "Invalid operation"

Any leading or trailing white space should be removed:

LogLineParser.message('[WARNING]:  Disk almost full\r\n')
// Returns: "Disk almost full"

2. Get log level from a log line

Implement the LogLineParser.log_level method to return a log line's log level, which should be returned in lowercase:

LogLineParser.log_level('[ERROR]: Invalid operation')
// Returns: "error"

Implement the LogLineParser.reformat method that reformats the log line, putting the message first and the log level after it in parentheses:

LogLineParser.reformat('[INFO]: Operation completed')
// Returns: "Operation completed (info)"
