New FAB component

[ferretwithaberet]

Hey there, I made a new FAB (Floating Action Button) component using react-native-ui-lib. I am posting it here in case you want to add it to the lib. It should be able to be integrated with minimal changes to the provided code.

It is actually 4 components:

• FAB.Button (Just a round Button, no positioning);
• FAB (Absolutely positioned FAButton);
• FAB.SpeedDial (Absolutely positioned FAButton which, when pressed, displays other buttons in an overlay);
• FAB.SpeedDial.Item (Used to define the buttons displayed inside of SpeedDial).

My calculations might be wrong for iOS, will test tomorrow in the simulator and update the gist.
