/*
 NOTE that this function isn't tested with an API key yet. There's a chance that
 you have to change the value of dataType: "json" to "jsonp" in the .ajax call.
 
 I'll obviously update this once I have an API key.
 
 If you don't have an API key, you can do the following:
 1) go to http://api.tumblr.com/v2/blog/{YOUR BLOG NAME}.tumblr.com/posts?api_key=PyezS3Q4Smivb24d9SzZGYSuhMNPQUhMsVetMC9ksuGPkK1BTt
 2) save that file as "tumblr.json"
 3) call the tumblr function from index.html with the following:
   tumblr({feed_url:'/path/to/tumblr.json', ...other options...})
   
 This will load the local json file instead of the remote file.
