+>  NVPSystem is a utility class to handle some basic system
+functionality that all projects likely make use of.
+It does not require any window to be opened.
+Typical usage is calling init right after main and deinit
+in the end, or use the NVPSystem object for that.
+init
+- calls glfwInit and registers the error callback for it
+- sets up and log filename based on projectName via nvprintSetLogFileName
