Description

Added a new module, pbhs, to track game high scores easily. This can be used as a drop-in module with any game, simply use the commands

let phs = require("pbhs").initPipboyHighScores();

phs.addHighScore(gameName, score) //returns true if adding the score succeeds
phs.readHighScores("piptris") //returns an array of scores

App to view high scores for every game will come later.
