/**
 * @description
 * Create a button with a given label or image or both
 *
 * @param {string} label The label the new button should carry
 * @param {string} image A string (URI) to image file or jQuery object of an image to add
 * @param {title} title The title attribute (tooltip) for the button
 * @param {Function} callback The callback function that should be invoked when the button is pressed. NOT a string but a "pointer" to a function
 *
 * @example
 // Create the button
 var $myButton = $createButton("My Button", "//example.myurl.it/myurl.png", "Starts the self destruction", function(e) {
    alert("This is inside an anonymous function (a function that does not have a name it could referenced to). Someone clicked the button!");
 });
 // Append the button to the DOM
 $myButton.prependTo("#content");

 * @example
 // Create a reference to the content-element for faster execution
 var $content = $("#content");
 // Creates two buttons and append/prepend it in an element
 var _aFunction = function(e) {
    alert("This is called from within a named function. You can use named functions to handle multiple events.");
 };
 $createButton("A Button", "", "Does this stuff ...", _aFunction).prependTo($content);
 $createButton("A second Button", "", "Does the same stuff ... but looks different", _aFunction).appendTo($content);
