Correction: is/isn't alias should be "===" and "!===" not "==" and "!="

Under https://autotelicum.github.io/Smooth-CoffeeScript/interactive/interactive-coffeescript.html#part-v.-reference-and-index

There is a list on the bottom of aliases, it lists is and isn't as with double ==, which is false, it actually compiles to triple equals, which is the identity operator.
