first commit of a working decorator.js
fixed decorator.js. Major fixes: moved counter var to countDecorator scope, replaced args with arguments keyword, change fn.call to fn.apply to accomodate arguments keyword.
Changed var counter line back to original, but in the new scope.
changed decorator.js to forward the function call, increment the count, and store the count in a property of the function
fixed 'return forward'
removed the extraneous assignment info
