Simple Color Log

This is a simple logger that uses standard log levels and prints the file name, line number, and timestamp for each log message. The log levels are as follows:

• FATAL
• ERROR
• WARN
• INFO
• DEBUG
• TRACE

The logger's level is set through the feature flags. These are the allowed feature flags:

• error
• warn
• info
• debug
• trace

The logger will only print messages that are at or above the level set by the feature flag. The default level is info.
