Solution for "four fours" problem

Fours

A partial solution to the problem posed here: https://twitter.com/mikelikesbikes/status/1396159019837018117

This solution represents the expressions in reverse Polish notation (RPN) - see also Forth and HP48s.

The version presented here does NOT produce all values from 1 to 100, as it does not use enough operators.

Extending the search to additional operators only requires adding the value to @operators and a clause to eval to handle it.
