Creating event-form component
Looking at our finished product now, if we click on any calendar day, we get this add
event dialog coming up.
You'll notice that it pops up exactly where you click.
Obviously, it's going to recognize which day you've clicked on, but the form itself will
position it itself to be near your mouse pointer.
So just inspecting the DOM to see how this works basically, this is obviously a; it has
an absolute position and it's influenced by where you click on the screen.
