FEATURE REQUEST - Snap to grid toggle button, which works in conjunction with Ctrl and other buttons

[abhiraaid]

At the moment, Flexi Bezier works independent of the snapping features of Blender. So no button to toggle the snapping to grid. It would be nice to have a toggle for all snapping - Grid, Angle, End Vertex, which in turn turns off when we click Ctrl when it's already toggled on. Just like default Blender. I'm not sure how things work from a programmer's perspective. But I hope this can be implemented Thanks again for the amazing add-on.
