The API is rather straight-forward, simply create a new logger and then you can use it as such:
import gogga;
GoggaLogger gLogger = new GoggaLogger();
gLogger.info("This is an info message");
gLogger.warn("This is a warning message");
gLogger.error("This is an error message");
This should output something like the following:
Various styles are supported which can be set using mode(GoggaMode)
