/*
Bit shifting with overflow protection using overflow operator "&".
Approach is consistent with standard overflow operators &+, &-, &*, &/
and introduce new overflow operators for shifting: &<<, &>>

Note: Works with unsigned integers values only

Usage

var i = 1       // init
var j = i &<< 2 //shift left
j &<<= 2        //shift left and assign
