/**
* [description]
* Takes an array of Game Objects, or any objects that have a public `y` property,
* and then adds the given value to each of their `y` properties.
*
* The optional `step` property is applied incrementally, multiplied by each item in the array.
*
* To use this with a Group: `IncY(group.getChildren(), value, step)`
*
* @function Phaser.Actions.IncY
* @since 3.0.0
*
* @param {array} items - An array of Game Objects. The contents of this array are updated by this Action.
* @param {number} value - [description]
* @param {array|Phaser.GameObjects.GameObject[]} items - The array of items to be updated by this action.
* @param {number} value - The amount to be added to the `y` property.
* @param {number} [step=0] - This is added to the `value` amount, multiplied by the iteration counter.
* @param {integer} [index=0] - An optional offset to start searching from within the items array.
* @param {integer} [direction=1] - The direction to iterate through the array. 1 is from beginning to end, -1 from end to beginning.
