toGraph(Number)

This method will convert a integer to an array of 0 and 1

var invader = '356190145855031919348890157738898011538149755602338030'
var pixels = tupper.toGraph(invader)

Which can later be used to print into a canvas:

pixels.forEach((row, y) => {
  row.forEach((pixel, x) => {
    ctx.fillStyle = pixel ? 'black' : 'white';
    ctx.fillRect(x * 5, y * 5, 5, 5);
  })
})

toNumber(Array)

This method will convert an array of 0 and 1 into Tupper's decimal

var pixels = tupper.toNumber([[0,0,0,0,0,0, ...)
