Add Callback, new tip position & more parameters..

[madeindjs]

Hello,

I used your library on my personal project. This really helped me but I needed some Knot callbacks. So I fork your project and improve it to fit more to my need. Here improvement

add Knot Callback (as proposed in my last PR)

I simply add basic callback parameters when you draw your TimeKnots. Bellow a very simple example:

TimeKnots.draw("#timeline1", kurbickFilms, {
  dateFormat: "%B %Y", color: "#696", width:500, showLabels: true, labelFormat: "%Y", 
  onMouseOver: function(circle, tip){console.log("you mouse overed :"+tip.text())},
  onMouseOut: function(circle, tip){console.log("you mouse out :"+tip.text())}
});

fixed tip position

In this mode, Tip are continously showed up on the top of the timeline and hover a circle update it. You have only to set tipPosition parameter to top.

add more visual parameters

I separate color in categories : Timeline, Tip & Circle. Here parameters

• colorTimeline: color used for the Timeline (default: 999)
• colorTip: color used for text visualization (default: rgba(0,0,0,.5))
• backgroundCircle: Background color of the circle (default: FFF)
• backgroundTip: Background color of the tip (default: {0,0,0,.5})

Factorize your code

I found many repettions and I foctorize it in function
