Tests failing, 'F' and 'T' undefined

Hi,

I just found this package while prototyping one of my projects and it seems to do the job just fine despite not being maintained. However, I can't get tests to work due to undefined references to 'F' and 'T'.

Result of 'npm test' below:

scrap
   > when it contains the html modifier pre parse function
     1) should apply it before loading it into cheerio
   > when it can reach the site
     2) should retrieve the content
   > when it cant find the page
     3) should return an error

Any hint where those two functions come from?

Start with test/scrap.test.js at the failing lines and compare those references with lib/scrap.js, especially the callbacks around lines 15-36. Run npm test to reproduce the three failures; done means the undefined references are resolved and all three tests pass.
