 * with real args

/**
 USAGE
 =====
 
 BASIC
 ----------------
 Each url is degined as a method, for example POKE.url_maps.example() would return a url
 to www.example.com/example.
 
 ADVANCED
 ----------------
 Some urls may require placeholder arguments for django to perform the reverse url method, so we might define this like:
 {[%] url example1 arg1,arg2 [%]}
 This script has a method fo swapping placeholder args with the desired correct args, for example:
 POKE.url_maps.example2 = function(arg1, arg2) {
   dict = {
    arg1: {
      placeholder: 'arg1',
      arg: arg1
    },
    arg2: {
      placeholfer: 'arg2',
      arg: arg2
    }
    return this.reaplce_holders('{[%] url exaple2 arg1,arg2 [%]}', dict);
   }
 }
 this will return back a url with the corret arguments, you can then call this:
 POKE.url_maps.example2(21312, 4823);
 which will return something like:
 www.example2.com/example2/21312/4823/
 Which you can then use in an ajax call 
 
 There is probably a more eligant way of achieving this, if you think of a way let me know :)
 
 Note: django template ({%) tags in these comments are noted as {[%] url [%]} to prevent django from interpreting these as real
 requests.
