README.md

I was thinking that through the use of the require in modulea, I'd be able to get a reference to the app based on what I thought I understood from http://requirejs.org/docs/api.html#circular. But, apparently I am wrong? :) Instead I get Uncaught Error: Module name "app" has not been loaded yet for context: _

app.js

define( [ "app/modulea" ], function ( modulea ) {
    return {
        init: function() {
            modulea();
        },
        someFunction: function() {
            
        }
    };
});

main.js

require( [ "app/app" ], function( app ) {
    app.init();
});

modulea.js

define( [ "require", "app/app" ],
    function( require, app ) {
        //"a" in this case will be null if a also asked for b,
        //a circular dependency.
        return function( title ) {
            return require( "app" ).someFunction();
        };
    }
);

I'm not sure I follow, I think you wanted to say require('app/app') inside modulea. If that is the case, then in app.js, I would also do require('app/modeula').
