Simple panel design and documentation

Actions:

• Panel can be moved with drag/drop on the title bar
• Clicking "Button" will trigger an alert pop up with "HELLO"
• Ticking the checkbox will change a variable CheckboxTicked = True and viceversa when unticked
• Dropdown menu is a classic drop down with 3 items: "Option 1", "Option 2", "Option 3". Once a selection is made a variable DropdownOption is updated to the Option selected
• Number box is a classic number box for a number with 2 decimals and 2 buttons (arrow up and down) to increment or decrement the number of 0.01 and update a variable NumberBoxValue
• Submit when clicked will trigger a popup that shows the status of the checkbox, the selected option of the dropdown and the number of the number box. Said values must be read directly from the elements and NOT using the previously used variables CheckboxTicked, DropdownOption and NumberBoxValue
