Motivation and Context
This PR provides the implementation of a selection box using the cursor in order to select multiple elements without the use of the keyboard.
Description
Every time the user clicks OUTSIDE an element, the selection box is created. In order for it to become visible, the user needs to drag the cursor. An element needs to be contained FULLY within the selection box for it to be selected when the selection box is released (i.e. the click/drag action is over). This feature also works when pressing the SHIFT key without deselecting the already selected items.
If the user's cursor goes outside the scope of the canvas while the selection box is active, the selection box will "freeze", but it will continue when the cursor comes back to the canvas. If the user releases the click while the cursor is outside the canvas and they return to the canvas, the selection box will remain active; clicking again will "resume" the selection box and the user can continue to drag the cursor in order to change the already active selection box before releasing it.
