restart animation

[jeremymauro]

I needed to restart the animation when a user clicks a button. I added this to the AnimatedMarker.js file

  reStart: function(latlngs){
    this.initialize(latlngs);
    // Don't show CSS transition back to initial position
    this._icon.style[L.DomUtil.TRANSITION] = ('all ' + 0 + 'ms linear')
    this._shadow.style[L.DomUtil.TRANSITION] = ('all ' + 0 + 'ms linear')
    // Reset marker to initial position
    this.setLatLng(this._latlngs[0]);
    var that = this;
    setTimeout(function(){
      that.start();
    }, 200)
  }

...and this to my onclick handler

animatedMarker.reStart(line.getLatLngs());

There may be a better solution, but this is working for me.
