Math: Average

Performs average across an array. If $a is an array and $b is an array, each member of $a is averaged against the same member in $b. If $a is an array and $b is a number, each member of $a is averaged agained $b. If $a is an array this array is averaged to one number. If $a is a number and $b is not provided or NULL, $a is gracefully returned as an average value of itself.
