posts.js

//the code below will embed replace [gist id=x] tags with an embedded gist similar to the way the Wordpress Gist 
//plugin works. I wrote this in order to import posts from Wordpress. See //GB: for the changes.

// **takes:** filter / pagination parameters
browse: function browse(options) {
    options = options || {};

    // **returns:** a promise for a page of posts in a json object
    //return dataProvider.Post.findPage(options);

        var i = 0,
            omitted = result, html;

            omitted.posts[i].author = _.omit(omitted.posts[i].author, filteredUserAttributes);
            omitted.posts[i].user = _.omit(omitted.posts[i].user, filteredUserAttributes);
            html = omitted.posts[i].html;
