Leveled logger wrapper for native log package

The main idea is to add Levels to log operations and ability to show logs from exact level or above.

Leveled logger (llogger) library allow you to add necessary logging everywhere in your code with related level. There are several levels: FATAL, ERROR, WARN, INFO, DEBUG.

import "gopkg.in/jurka/llogger.v1"

log := llogging.NewStdLogger(llogging.INFO, "")

x := 1
log.Info("This is x =", x)

log.Debug("Cheking for x != 10")
if x != 10{
	log.Error("X has wrong value!")
}
