Class Avg

Prefix operation that return the average of a set of numbers

Operand Count: 0 to infinite

Operand Type: number, if the operand count is 1, it can be an array

Output Type: double

Usage: avg(1, 2, 3, 4, 5) or avg(@(1, 2, 3, 4, 5))

Note: null value will not be counted, therefore avg(null, 2, 2, 2) should be 6/3 = 2 not 6/4 = 1.5; It will return null if the count is 0.
