Add JSON Output Format

Add Dash Hover Over.

Benefits

1. Using Hovering Over the dashboard, we can use it for picking the needed cell, highlighted it, and with pop up message request confirmation (model box can be created with HTML and CSS) move the 3D model to the needed location. It is some kind of duplication of the Replace button. Main idea to add interactivity to the app.

2. In Dash Hover Over returns you JSON Output format. It is useful for parsing and if we would use some Databases and Pandas for more common way.
