Adding Drag and Drop features to the pieces

[ashishpapanai]

JQuery offers certain tools to get the source i.e. the position from where the user started to drag to the position where the user has left the object.
ChessJS expects the participant to get the start and the end co-ordinates of the drag and drop so that the maintainers can work on implementing this feature.

People prefer dragging and dropping the pieces from the source to the destination of the piece to clicking the piece and the destination square.
