A callback that is called when a component is ready. Does not have any
paramters and any callback value will be ignored.

@callback Component~ReadyCallback
@this Component
 
Creates an instance of this class.

@param {Player} player
The `Player` that this class should be attached to.

@param {Object} [options]
The key/value store of player options.

@param {Object[]} [options.children]
An array of children objects to intialize this component with. Children objects have
a name property that will be used if more than one component of the same type needs to be
added.

@param {Component~ReadyCallback} [ready]
Function that gets called when the `Component` is ready.
