modified init to be applied more than once

[madebits]

Hi,

I modified mermaid.init() so that it can be applied more than once. This is needed in my case to load content dynamically on the page. You may consider adding this minor change upstream.

var init = function () {
    var arr = document.querySelectorAll('.mermaid');

    var cnt = 0;
    for (i = 0; i < arr.length; i++) {
        var element = arr[i];

        // added code
        if(!element.getAttribute("data-processed")) {
            element.setAttribute("data-processed", true);
        } else continue;
...

Thanks, v
