vertex-logger (vlog)

Vertex Logger (or vlog) is a simple logging library for Golang. This library is used in Vertex to log messages to different outputs:

• stdout
• stderr
• text file
• JSON file

For text and JSON files, the library open a new file every day. This allows to keep a clean history of the logs, without having huge log files for larger projects.
