Housekeeping

• Updated and removed unnecessary dependencies
• Replaced lodash for lodash.throttle

Events

New events are added affixed and unaffixed. See sample usage below:

menu.on('affixed', () => {
  console.log('Menu is affixed.');
});

menu.on('unaffixed', () => {
  console.log('Menu is unaffixed.');
});

Added Mirror Positioning

When position are set to mirror, the element is cloned and appended to the <body/>. This mirror element will act as the fixed position element in place for the original element. This is more performant than absolute where necessary.

Added Throttling

Replaced rAF with lodash throttling
