A simple Rust logger.
Usage
To log messages, first set up the default path and log level like so:
If logging to a file is not necessary, simply set the path to an empty string, like so:
set_path;
Then to log messages, call the log() function:
use *;
For clarity, opt to explicitly state the package name when calling set_path() and set_level().
To write the message to a different path than the default, change the None parameter to Some("/custom/path/here").
