unable to run on Runkit.

[DeanKamali]

I'm unable to test via runkit.

Even tho tests pass

> mocha
  unbracket
    unbracketWithParenthesis
      ✓ should unwrap items insides parenthesis
      ✓ should unwrap items and not care about nested parenthesis
    unbracketWithBrackets
      ✓ should unwrap items insides brackets
    unbracketWithCurlyBraces
      ✓ should unwrap items insides curly braces
    unbracketWithRafters
      ✓ should unwrap items insides rafters
  5 passing (10ms)

I'm getting the following when I use it on my code.

                           
TypeError: unbracket.withParenthesis is not a function
