Usage

var drag = new Drag('elem'); // elem can be .class, #id or tag name
// all these elements are now draggable !

// multi use :
var drags = [
    new Drag('.class'),
    new Drag('#id'),
    new Drag('tag')
];

// it can be object :
var drags = {
    type_1: new Drag('.class'),
    type_2: new Drag('#id'),
    type_3: new Drag('tag')
};

Options

// possible options: axis, grid, container
// you can set 1, 2 or 3 options on same Drag

var drag = new Drag('elem', {
    axis: 'x' || 'y', // choose x or y - string type
    grid: [10,50], // choose a Xstep and Ystep. Even if you set x axis, you must write Ystep - array type
    containment: 'elem2' // choose the non-traversable area of draggable elem - string type
});

Listeners

// possible event: dragmove, pointerup, pointerdown
drag.on('event', () => { // function() {}
    // code
});

Know if there is current dragging element :

// null if there is not
if(drag.dragging) {
    // code
}

    height: ,   // html element height (shortcut of drag.dragging.$element.getBoundingClientRect().height)
    position: {
        x: ,    // current X position of element while dragging - relative to the page
        y:      // current Y position of element while dragging - relative to the page
    },
    relativePosition: {
        x: ,    // current X position of element while dragging - relative to the last drop position
        y:      // current Y position of element while dragging - relative to the last drop position
    },
    startingPosition: {
        x: ,    // X position of dragging element before the drag - relative to the page
        y:      // Y position of dragging element before the drag - relative to the page
    },
