## Background
We all know about "balancing parentheses" (plus brackets, braces and chevrons)
and even balancing characters that are identical.
Read that last sentence again, I balanced different characters and identical
characters twice and you didn't even notice... :)

If a = 1, b = 2, c = 3 ... z = 26
Then l + o + v + e = 54

So friendship is twice stronger than love :-)

See https://www.codewars.com/kata/reverse-polish-notation-calculator
Your job is to create a calculator which evaluates expressions in Reverse Polish notation.
For example expression 5 1 2 + 4 * + 3 - (which is equivalent to 5 + ((1 + 2) * 4) - 3 in normal notation)
should evaluate to 14.
For your convenience, the input is formatted such that a space is provided between every token.
Empty expression should evaluate to 0.
Valid operations are +, -, *, /.
You may assume that there won't be exceptional situations (like stack underflow or division by zero).
