Subject: [PATCH] Add missing index declaration

When using the postApply function from undoToRange() on multiple ranges this error occured :

ERROR ReferenceError: i is not defined
    at ClassApplier.postApply (rangy-classapplier.js:741)
    at ClassApplier.undoToRange (rangy-classapplier.js:976)
    at HighlighterDirective.undo (***.directive.ts:52)
    at HighlighterDirective.set ranges [as ranges] (***.directive.ts:19)
    at updateProp (core.js:32189)
    at checkAndUpdateDirectiveInline (core.js:31867)
    at checkAndUpdateNodeInline (core.js:44367)
    at checkAndUpdateNode (core.js:44306)
    at debugCheckAndUpdateNode (core.js:45328)
    at debugCheckDirectivesFn (core.js:45271)

This error is simply due to missing "let" in line 744.

Thanks for your pretty good library ;)
