Caveats
-------
Get funky!
----------

- If you override the 'text json' converter, this will not work.
Version 1.1 has been slightly refactored for the sake of adding some robustness. A fun side-effect is that we can now register revivers in a couple more funky ways.

#### Multiple revivers for same key.

// Why you'd want to do this? No one knows, but it works!
$.ajaxReviver({
created_at: [
function( v ){ return new Date(v); },
function( v ){
return v.getTime();
}
]
});

#### Same as above, different syntactic approach.

$.ajaxReviver([
'created_at',
[
function( v ){ return new Date(v); },
function( v ){ return v.getTime(); }
]
]);

#### Mixed sytax! Aka: I dont know what I'm doing, but it seems to work.

$.ajaxReviver([
'created_at',
function( v ){ return new Date(v); },
{ published_at: [
function( v ){ return new Date(v); },
function( v ){ return v.getTime(); }
] },
function(key,value){
if( key === 'nested') return {};
return value;
}
]);

Caveats
-------

- If you override the 'text json' converter, <del>this will not work</del> <ins>It will be processed before revivers but adds overhead as it must be re-stringified for JSON.parse to "revive" it again. This behavior may change in subsequent versions.</ins>
