Created October 5, 2017 19:35

	/**
	* Calculates weighted average with latter values weighing more.
	*
	* Weights for each value are calculated using https://en.wikipedia.org/wiki/Weighted_arithmetic_mean#Exponentially_decreasing_weights
	*
	* The average itself is calculated by summing up each value multiplied by its weight: https://en.wikipedia.org/wiki/Weighted_arithmetic_mean#Convex_combination_example
	*
	* @param {number\|Array<number>} values Values, of which to calculate average
	* @param {number} delta Delta, 0 < delta < 1, basically, how much weight the latest value will have when calculating average
	* @return The input multiplied by 2.
