inline images for markers

[tjaartvdwalt]

Would it be possible/sensible to allow inline base64 encoded icons for cluster markers? I use this for google maps markers.

One possible option I can see, is to set the imagePath option to an object. For example:

var options = {
            imagePath: {
               '1': 'data:image/png;base64,.....',
               '2': 'data:image/png;base64,......'
            }
}

I realized that it probably makes more sense to just have the imagePath as an array. I submitted a pull request #7 for this.

The usage would be:

var options = {
    imagePath: ['data:image/png;base64,.....', 'data:image/png;base64,.....']
}
