 Currently the library offers the following API's
 
  - `toggleMenu`: Open or close the menu depending on its current state.
+ - `setRadius`: Set the radius of the arc menu.
  - `isMenuOpened`: Returns whether the menu is opened or closed.
  - `setAnimationTime`: Controls the animation time to transition the menu from close to open state and vice versa. The time is represented in milli-seconds
  - `setStateChangeListener`: Allows you to listen to the state changes of the Menu, i.e. `onMenuOpened` and `onMenuClosed` events
